- HISTORY
- -------
- Jan 10, 1997 - Release 1.1
- Improved.
- The binary output format for filters remains unchanged.
-
- - Release 1.0
- Available with beta 1 of ModelMaker 1.5.
-
-
- INTRODUCTION
- ------------
-
- Streams & Containers 1.0 is Freeware (more info see Disclaim.txt) and contains
- 16 bits Delphi 1.0 units CONTAINR and FILTERS which implement and extend BP7.0
- style collections and streams.
-
-
- DESCRIPTION
- -----------
-
- TFilter is a TStream descendant which adds the Put / Get object streaming
- capabilities to a TStream instance. TFilter does not actually read or write
- data but delegates this to an attached stream. This stream can be owned or not.
-
- Filters adhere to the decorator pattern.
- Filters can be cascaded:
- Filter1 => Filter2 => Filter3 => TStream. (such as TFileStream)
-
- Some additional filters are included:
- - BufferedFilter buffers it's IO
- - BufFileFilter is a combination of a TBufferedFilter with a TFileStream
- - TCycleFilter is a filter that is able to read and write cyclic object
- structures like: Parent saves children and children save their parent.
- - TClipBrdFilter reads and writes is a binary clipboard stream, allowing you
- to stream classes to the clipboard the same way you stream them to a file
- - TOffsetFilter which lets you treat a section in an other stream as new
- complete stream, including Position := 0, Size etc.
-
- Utility procedures include
- - Reading and writing of PChar and TStrings from/to a TFilter
- - Copying a TStreamable instance by first putting it to memory and then getting
- it back.
-
- For classes to be streamable, they HAS TO be a TStreamable descendant AND be
- registered as streamable using the RegisterStreamable procedure.
-
- TContainer is an abstract base class which defines an interface for list like
- data types. TCollection is a direct descendant which implements a TContainer
- using a Delphi 1.0 TList class. TCollection add to TList
- - Ownership of items (property OwnesItems)
- - Sorting of list (property Sorted / CanSort)
- - Duplicate behavior (property Duplicates)
- - OnChange notifications
- - Streamable behavior (TContainer is a streamable class) allowing you to Put a
- whole container at once on a stream: Filter.Put(List)
-
- This version of FILTERS and CONTAINR fix some bugs and extend the
- exiting functionality.
