An HTTP server has been installed at the Centre Universitaire d'Informatique
of the University of Geneva.  Information about various research groups at
the CUI is available, as well as a number of other experimental services.

The Object Systems group at CUI is providing a number of pointers to
Object-Oriented Information Sources available on the World Wide Web.
The page containing these sources is accessible from the CUI home page.
The URL is: http://cui_www.unige.ch/home.html

You must have a WWW browser to access the information.  If you do not have
a browser, you should obtain, for example, the xmosaic browser from:
ftp.ncsa.uiuc.edu:Web/xmosaic or info.cern.ch:pub/www.

The material available from CUI is in an early stage of development.
Suggestions for additional OO references to include (or whatever) are welcome!

>29  Actors Paper (UIUC)

From: [e-mail] (Gul Agha)
Subject: Actor Theory Paper available

Date: Wed, 4 Aug 1993 15:41:02 GMT

A new paper providing a definitive and detailed development of the
semantics of actor systems is available via anonymous ftp.  Comments
are especially welcome.


Title:          A Foundation for Actor Computation

Authors:        Gul Agha, Univerity of Illinois at Urbana-Champaign
                Ian Mason, Stanford University
                Scott Smith, John Hopkins University
                Carolyn Talcott, Stanford University

Abstract:

        We present an actor language which is
        an extension of a simple functional language, and provide a precise
        operational semantics for this extension.  Actor configurations are
        open distributed systems, meaning we explicitly take into account the
        interface with external components in the specification of an actor
        system.  We define and study various notions of equivalence on actor
        expressions and configurations.

 Yes, the Law of Demeter paper is available in electronic form on the
 net. Indeed, many of the Demeter project papers are available from
 the ftp server at Northeastern University (see instructions below).

 The Law of Demeter idea has been automated in the Demeter Tools/C++
 as an adaptive software tool which automatically makes much of your C++ code
 compliant with the Law of Demeter. The tool is an add-on tool to
 your favorite C++ development environment and is commercially available
 from Demeter International. The Demeter Tools/C++ lift
 object-oriented programming to a higher level of abstraction
 by allowing the user to focus on the essential and
 stable classes. A paper on ADAPTIVE SOFTWARE will appear in
 the Communications of the ACM and is also available from the
 ftp server.

The measurements done as part of the work here on the Mushroom project
show that temporal locality within Smalltalk objects is great (and
hence even conventional caches work reasonably well [unless the GC
scheme trashes the cache]), whereas spatial locality on a scale much
larger than the average object (which is 40 bytes) is much harder to
come by.

>34  Pred Classes (Cecil)

What: "Predicate Classes" paper
From: [e-mail] (Craig Chambers)
Date: Fri, 30 Apr 93 01:25:02 GMT

"Predicate classes are a new linguistic construct designed to
complement normal classes in object-oriented languages. Like a normal
class, a predicate class has a set of superclasses, methods, and
instance variables. However, unlike a normal class, an object is
automatically an instance of a predicate class whenever it satisfies a
predicate expression associated with the predicate class. The
predicate expression can test the value or state of the object, thus
supporting a form of implicit property-based classification that
augments the explicit type-based classification provided by normal
classes. By associating methods with predicate classes, method lookup
can depend not only on the dynamic class of an argument but also on
its dynamic value or state. If an object is modified, the
property-based classification of an object can change over time,
implementing shifts in major behavior modes of the object. A version
of predicate classes has been designed and implemented in the context
of the Cecil language."

Comments on the ideas in the paper are appreciated.

OBJECT DESIGN'S RESULTS ON THE OO7 BENCHMARKS
April 26, 1993

We have made a copy of our results available to the Internet community. You
can access this information through anonymous ftp from ftp.odi.com in the
file /pub/oo7/results.ps.

The report includes the "official" tests done for ObjectStore by the
University of Wisconsin, and our internal execution of all the tests using
ObjectStore Release 2.0.1, the current production version.  As the report
shows, our internal execution carefully followed the agreed-upon procedures
for running OO7, and we believe the numbers that were produced accurately
represent ObjectStore's performance.

I have created an experimental service for remote users to try some of
our graph layout programs through Internet mail, for research or
educational purposes.  I'm looking for a few friendly users to try this
service.  The programs are:

    dag (directed graphs, old, program, works with some USL C++ utilities.
                This may have unintentionally sparked the apparently misdirected
                discussion of "DAG classes" in one newsgroup recently.)
    dot (directed graphs, newer algorithms, better layouts, more features)
    neato (undirected graphs, compatible with dot, Kamada-Kawai spring embedder)

You can ftp PostScript files of documentation from dist/drawdag/*.Z on
research.att.com

To draw graphs, send a graph file to [e-mail]
and give the command line in the Subject header.  For example,

>38  C++SIM (Simula-like Sim Pkg)

From: [e-mail] (Mark Little)
Subject: C++SIM Release 1.0 Announcement
Organization: Computing Laboratory, U of Newcastle upon Tyne, UK NE17RU
Keywords: C++, SIMULA, simulation, object-oriented
Date: Mon, 14 Jun 1993 15:02:33 GMT

C++SIM 1.0 Release Announcement.

This is to announce the release of version 1.0 of C++SIM, a simulation
package written in C++. C++SIM provides discrete process based
simulation similar to that provided by the simulation class and
libraries of SIMULA. The linked list manipulation facilities provided
by SIMSET are also included in the package.

Inheritance was used throughout the design to an even greater extent
than is already provided by SIMULA. This has allowed us to add new
functionality without affecting the overall system structure, and hence
provides for a more flexible and expandable simulation package.

A paper is included which describes the design and implementation of
C++SIM and includes a worked example of how to use the package. The
paper describes the class hierarchy which we have created, and
indicates how it can be used to further refine the simulation package.

The simulation package requires the use of a threads package and
currently only works with Sun's lightweight process library or the Gnu
thread package (which *is* included in the distribution). The package has
been used on Sun workstations, and, with the exception of the thread
library requirement, contains no system specific code which should make
porting to other systems relatively easy. The code has been compiled
with Cfront 2.1 and Cfront 3.0.1 and g++ 2.3.3

If you find any bugs or make modifications (e.g., ports to other thread
packages) or port it to other systems, then please let me know so I can
keep the sources up-to-date for other users.

The package is available via anonymous ftp from arjuna.ncl.ac.uk

>40  C++ Signatures (subtyping)

From: [e-mail] (Gerald Baumgartner)
Newsgroups: comp.object,comp.lang.c++
Subject: signature implementation for G++ 2.5.2 and tech report available
Date: 4 Nov 1993 12:03:00 -0500
Organization: Department of Computer Sciences, Purdue University

Announcing the paper

    Signatures: A C++ Extension for
    Type Abstraction and Subtype Polymorphism

    by Gerald Baumgartner and Vincent F. Russo.
    Tech report CSD-TR-93-059, Dept. of Computer
    Sciences, Purdue University, September 1993.
    Submitted to Software Practice & Experience.

and a beta release of our implementation of

    signatures for GCC 2.5.2.


 How to Get that Stuff?
 ----------------------

You can get both the paper and the implementation by ftp from

    host:        ftp.cs.purdue.edu    (128.10.2.1)

    login:        anonymous

    password:    your e-mail address

    directory:    pub/gb

    files:        COPYING            Copyright notice.

            README            This file.

            Signatures.{dvi,ps}.gz    DVI and Postscript versions
                        of the paper.

            gcc-2.5.2.sig.diff.gz    Patch to upgrade GCC 2.5.2.

            test.tar.gz        Test files and script to run
                        the tests.

To make GCC 2.5.2 understand signatures, just copy the context diff
file into the GCC source directory, type

    gunzip gcc-2.5.2.sig.diff.gz
    patch < gcc-2.5.2.sig.diff

and rebuild and install `gcc,' `cc1plus,' the man pages, and the manual.

For compiling C++ code containing signatures, you need to use the
command line option

    -fhandle-signatures

We tested our extension on Sun 4 only, but since there are no changes
to the compiler backend, it is expected work on other architectures as
well.  To test whether it works on your architecture, unpack the file
`test.tar.gz' and run the shell script

    Test

It compiles the test programs and runs them.  If everything works
correctly, all the test programs (all 40 of them) should print

    Hello World.


 What are Signatures anyway?
 ---------------------------

Roughly, signatures are type abstractions or interfaces of classes.
They are related to ML's signatures, categories in Axiom, definition
modules in Modula-2, interface modules in Modula-3, and types in
POOL-I.

The main language constructs added are signatures and signature pointers.
For example, the signature declaration

    signature S
    {
      int foo (void);
      int bar (int);
    };

defines a new abstract type `S' with member functions `int foo (void)'
and `int bar (int).'  Signature types cannot be instantiated since they
don't provide any implementation.  Only signature pointers and signature
references can be defined.  For example,

    C obj;
    S * p = &obj;

defines a signature pointer `p' and initializes it to point to an object
of class type `C,' where `C' is required to contain the public member
functions `int foo (void)' and `int bar (int).'  The member function call

    int i = p->foo ();

executes then `obj.foo ().'

Class `C' is called an implementation of the abstract type `S.'  In
this example, we could have made `S' an abstract virtual class and `C' a
subclass of `S,' and we would have had the same effect.  The advantages
of signatures over abstract virtual classes are

    - you can build a type hierarchy separate from the class inheritance
      (implementation) hierarchy,
    - subtyping becomes decoupled from inheritance, and
    - signatures can be used with compiled classes, while you cannot
      retrofit an abstract virtual class on top of compiled class
      hierarchies.

For more information, please, see the paper.


 What's Implemented and what's not?
 ----------------------------------

Signature declarations and signature pointers are implemented and
working.  For examples of what's working and how to use them you can
have a look at the test files.

The following bugs are known:

      - The destructor of objects cannot be called though signature pointers.
      - A signature pointer cannot point to an object of a class defined
    by multiple inheritance.
      - The signature conformance check does not work if the signature
    contains other signature declarations or class declarations.
      - Operator and conversion operator member functions of signatures
    can only be called with function call syntax, such as
    `p->operator+(17),' but not with operator or conversion syntax.

The following language constructs and features are not yet implemented:

      - constants in signatures,
      - signature references,
      - signature inheritance,
      - the `sigof' (signature of a class) construct,
      - views (not even the parsing is done),
      - signature templates, and
      - exception specifications in signature member function declarations.

The following optimization is not implemented:

      - Looking up a virtual class member function through a signature
    pointer/reference requires double indirection.  This can be optimized
    by memoizing, so that only the first lookup of a member function
    requires double indirection and further lookups require only single
    indirection.

The items above are roughly in the order in which they will be implemented.

Besides bug fixes, the main features that have been implemented since the
last release are default implementations of signature member functions
and opaque types.

>41 The Texas Persistent Store

  The Texas Persistent Store, version 0.1

Texas is a simple, portable, high-performance and (best of all) FREE
persistent store for C++ using "pointer swizzling at page fault time"
to translate persistent addresses to hardware-supported virtual addresses.

Texas is built on top of a normal virtual memory, and relies on the
underlying virtual memory system for caching.  It uses user-level virtual
memory protections to control the faulting of data from a persistent storage
file into virtual memory.

All addresses in a page are translated from a persistent format to
actual virtual addresses when the page is brought into virtual memory,
and subsequent memory references (including pointer traversals) are
just as fast as for non-persistent data.

Texas is easy to use, and is implemented as a UNIX library.  It is small
and can be linked into applications.  It requires no special operating
system privileges, and persistence is orthogonal to type---objects may be
allocated on either a conventional transient heap, or on the persistent
heap, as desired.

Texas supports simple checkpointing of heap data.  A log-structured storage
module is under development, and will provide fast checkpointing of small
transactions.

Texas is beta software, and the current prerelease version supports only
simple single-machine operation.  Future releases will support client-server
operation, a flexible access control scheme, and transaction support.

Texas currently runs under SunOS and ULTRIX, using Sun CC or GNU C++.
Porting to other modern systems (e.g., OS/2, WNT, Mach) should be easy---it
requires only mprotect(), signal(), and sbrk() calls (or their equivalent)
to control virtual memory protection setting and trap handling.

Papers about the pointer swizzling scheme and Texas itself (referenced
below) are available via anonymous ftp from cs.utexas.edu (IP address
128.83.139.9), as postscript files swizz.ps and texaspstore.ps in the
directory pub/garbage.

The source code for Texas is also available, in the directory
pub/garbage/texas.

>42 OSE C++lib

From: [e-mail] (Graham Dumpleton)
Date: Tue, 16 Nov 1993 11:34:42 +1100 (EST)
Organisation: Telstra International
Phone: [phone]

  WHAT:

    OSE consists of three C++ class libraries, a build environment based on
    GNU make, programs for documentation extraction and other miscellaneous
    tools.

    The C++ libraries include generic classes and some UNIX specific classes.
    Collection classes use templates compatable with AT&T C++ 3.0. If you
    have a C++ compiler which does not support templates, a template
    preprocessor supplied with OSE can be used.

    OSE uses a GNU style configure script, making it relatively easy to
    install, even on platforms for which it may not yet have been compiled.
    For DOS users, a script is provided to create a copy of the C++
    libraries suitable for compilation on that platform.


  WHERE:

    OSE can be obtained via anonymous ftp from:

      Europe:

    ftp.th-darmstadt.de [130.83.55.75]
    directory pub/programming/languages/C++/class-libraries/OSE

behavior.  As I see it, predicate classes are a key step towards solving
one of the most frustrating problems of OO programming: the struggle
over whether to encode some difference among objects in the value of a
slot (that is one of its parts) or in the object's `method table' (class
or that which it is one-of).

A closely related problem, that has also come up in this series of
messages, is how so-called factory objects can dynamically select the
behavior of the objects they create.  We have developed a new OO
language concept called Traces, that can be used to make much more
powerful factory objects, as well as handle some of the things predicate
classes do.  The two ideas are similar in that they both make behavior
selection a much more dynamic phenomena.

My ISOTAS'93 paper presents the concept of Traces and shows it
application to some problems.  This paper is available for anonymous FTP
from ftp.parc.xerox.com, in the /pub/mops directory.  The file is
traces.ps.

Gregor

Following is the abstract from the paper:

Object-oriented techniques are a powerful tool for making a system
end-programmer specializable.  But, in cases where the system not only
accepts objects as input, but also creates objects internally,
specialization has been more difficult.  This has been referred to as
the ``make isn't generic problem.''  We present a new \oo{} language
concept, called traces, that we have used successfully to support
specialization in cases that were previously cumbersome.

The concept of traces makes a fundamental separation between two kinds
of inheritance in \oo{} languages: inheritance of default implementation
-- an aspect of code sharing; and inheritance of specialization, a
sometimes static, sometimes dynamic phenomenon.

>46 BeBOP(seq,par,LP,OO,meta)

From: [e-mail] (Andrew Davison)
Subject: BeBOP v.1.0 Available
Message-ID: <[e-mail]>
Organization: Department of Computer Sci, University of Melbourne
Follow-Up: comp.parallel
Date: Mon, 13 Sep 1993 04:08:41 GMT

 BeBOP and bp Version 1.0 now available
 ======================================

 What is BeBOP?
 ==============
The language BeBOP is a unique combination of sequential
and parallel Logic Programming (LP), object oriented
programming and meta-level programming.

The LP component offers both don't know non-determinism
and stream AND-parallelism, a combination not possible
with concurrent LP languages.

BeBOP's object oriented features include object IDs,
encapsulation, message passing, state updating, and
object behaviour modification.

The meta-level capabilities are based on the treatment
of Prolog theories as first order entities, which
enables them to be updated easily, and for fragments
to be passed between objects in messages.

BeBOP is implemented by translation down to NU-Prolog,
and its parallel extension, PNU-Prolog. An unusual
aspect of this is the way that object IDs are utilized
as a communication mechanism between objects.

 What is bp?
 ===========
The bp interactive interpreter supports BeBOP programming
by allowing the flexible invocation of objects, and
offering the means for setting up communication links
between objects at any time. An incidental benefit is
the ability to use `global' variables in queries. Since
bp is an augmentation of the NU-Prolog np system, objects
and Prolog goals can be combined, and a by-product is
that the floundering of Prolog queries is avoided.


 Where are they?
 ===============
The BeBOP system (BeBOP and bp), and the PNU-Prolog
preprocessor pnp, can be found at the anonymous ftp
site munnari.oz.au (128.250.1.21), in the directory
pub as the file bebop.tar.Z. Remember to use binary
mode when copying it.

The release comes with a user manual, several papers
(in Postscript format), sample programs, and source code.


 System requirements
 ===================
The BeBOP system requires the following:

* The NU-Prolog system, compiler and interpreter
* The pnp preprocessor
  (this is included as part of the BeBOP system release)
* GCC or similar compiler
* Yacc (or Bison) and Lex

We've done significant work in that area.  Check out the following tech
report:

D. B. Stewart, R. A. Volpe, and P. K. Khosla, "Design of Dynamically
    Reconfigurable Real-Time Software using Port-Based Objects,"
    Carnegie Mellon University Tech Report #CMU-RI-TR-93-11, July 1993.

    Abstract: The current development of applications for sensor-based
    robotic and automation (R&A) systems is typically a `one-of-a-kind'
    process, where most software is developed from scratch, even though
    much of the code is similar to code written for other applications.
    The cost of these systems can be drastically reduced and the capability
    of these systems improved by providing a suitable software framework
    for all R&A sys tems. We describe a novel software framework, based on
    the notion of dynamically reconfigurable software for sensor-based
    control systems. Tools to support the implementation of this framework
    have been built into the Chimera 3.0 Real-Time Operating System. The
    framework provides for the systematic development and predictable
    execution of flexible R&A applications while maintaining the ability to
    reuse code from previous applications. It combines object-oriented
    design of software with port-automaton design of digital control
    systems. A control module is an instance of a class of port-based
    objects. A task set is formed by integrating objects from a module
    library to form a specific configuration. An implementation using
    global state variables for the automatic integration of port-based
    objects is presented. A control subsystem is a collection of jobs
    which are executed one at a time, and can be programmed by a user.
    Multiple control subsystems can execute in parallel, and operate
    either independently or cooperatively. One of the fundamental concepts
    of reconfigurable software design is that modules are developed
    independent of the target hardware. Our framework defines classes of
    reconfigurable device driver objects for proving hardware independence
    to I/O devices, sensors, actuators, and special purpose processors.
    Hardware independent real-time communication mechanisms for
    inter-subsystem communication are also described. Along with providing
    a foundation for design of dynamically reconfigurable real-time
    software, we are also developing many modules for the control module,
    device driver, and subroutine libraries. As the libraries continue to
    grow, they will form the basis of code that can eventually be used by
    future R&A applications. There will no longer be a need for developing
    software from scratch for new applications, since many required modules
    will already be available in one of the libraries.

It's true!  On WUArchive (wuarchive.wustl.edu) there is a series of
slides developed in Microsoft's PowerPoint.  The course material
includes lesson plans, tests, and workbooks, along with full notes
accompanying each slide.

There's one _little_ catch -- it's in the Public Ada Library.  Now,
the OOP course (there's three courses, one on OOD, OOP, and Software
Engineering) covers both C++ and Ada.  It was designed to let the
students work in both languages to get an objective opinion of the
pluses and minuses of each language (gee, what a concept!).

The OOD slides do NOT cover OMT.  Some material is used from Booch's
OOD book, but not the notation.  From looking at the slides, it appears
very easy to insert your own notation.  The important part for students
is communicating the concepts, which (for the price) these slides do
a DAMN good job of. <- (Safire's Violation #45: "A perposition is a
bad thing to end a sentence with." :-)

Ah, but WHERE on WUArchive are they?  If you look under
languages/ada/crsware, I believe you'll find them.  Good luck!

For over six years, the primary focus of the Distributed Object Computing
Department within GTE Laboratories has been the Distributed Object
Management (DOM) project. The DOM project conducts research into
object-oriented technology for integrating heterogeneous, autonomous,
distributed (HAD) computer systems/resources. Major research areas include:
interoperable object models; interoperable, distributed object
architectures; heterogeneous, extended transaction models; and information
requests in HAD environments. We are experimenting in these areas using our
prototype DOM system which we have developed over the past five years. This
technology is based on ideas from a number of technical areas including
distributed, object-oriented, databases, multi-database systems, operating
systems, and programming languages.

>53  KEOBJ, OO DSP micro-kernel

From: [e-mail] (Chris Bidaut)
Subject: Object kernel for DSP & RISC processors
Date: Mon, 15 Nov 1993 22:48:46
Organization: Softia, Inc.

This is an announcement for KEOBJ, an object-oriented micro-kernel for Digital
Signal Processors (DSP) and RISC processors.  This is also a request for
comments from the Internet community. Feedback on the architecture and
programming interface will be appreciated and incorporated into the next
release.


1 DESCRIPTION
-------------

KEOBJ is an object-oriented micro-kernel optimized for advanced embedded
applications, and it particularly targets Digital Signal Processors (DSP)
and RISC processors in multimedia environments.

Its main features are object-orientation, real-time behavior, signal processing
support, micro-kernel architecture and scalability.

1.1 Object-orientation

The kernel is a collection of system classes exported to the applications
(e.g Process, Thread, Memory, ...).
An object name space provides a way to locate any public object (e.g. IPC,
memory) using a symbolic path.
The kernel is written in C++ and is easily portable.

1.2 Real-time behavior

The design stresses fast response time and predictability to qualify for the
real-time label. The kernel is reentrant and preeemptable.

1.3 Signal processing support

Besides providing an architecture appropriate for most general purpose
applications, the kernel incorporates dedicated features for signal processing
applications. This includes two phases interrupt processing, time-deadline
scheduling, Inter Process Communications, multiple memory pools, awareness of
the constraints due to a single data type (word).

1.4 Micro-kernel architecture

Probably the most important feature of the kernel is the ability to be
extended at run-time with new services such as devices drivers, public
classes (IPC, file systems, windowing systems). Applications and system
services are dynamically loaded by a COFF compatible loader.

The core kernel is customizable at run-time through a personality mechanism
to emulate other environments (Operating systems) or to tailor the processes
environments.

1.5 Scalability

The API supports physical and virtual memory organizations with the same
semantics.

Applications source code will be portable across DSP and RISC processors.

The architecture supports symmetric multiprocessing and distribution (Available
by mid-1994).

    MindFrame for Windows 1.0 Release Note
    ======================================

mndframe.zip (MindFrame for Windows) is available for anonymous ftp
on ftp.cica.indiana.edu. It is currently in /pub/pc/win3/uploads.

"MindFrame for Windows" is a freeware application developed to
teach an object modeling approach presented in the
book: "Object-Oriented GUI Application Development" Geoff Lee,
Prentice-Hall, 1993, ISBN 0-13-363086-2.

This application is useful in many other areas as well, for
example, in Bible studying (metaphors, parables, prophecies,
types), neural modeling, ecological modeling, and task modeling.
There are 20 sample applications covering these areas. There
are also description of each of the sample application in the
on-line Help. Read "About MindFrame..." help topic for more
information.

1. Installation Procedure:
   DOS> mkdir MndFrame
   DOS> cd MndFrame
   DOS> copy b:MndFrame.zip   (or where you kept the mndframe.zip file)
   DOS> unzip -d mndframe.zip  (extract files into subdirectories)
   DOS> copy grid.vbx \windows\systems (your local Windows system directory)

2. Running the application:
   . In Windows, open your "File Manager"
   . Go to \MndFrame directory
   . Find the MndFrame.exe file
   . Drag the MndFrame.exe file icon into a "Program Manager" window
