- binfo
-
The main data structure in the compiler used to represent the
inheritance relationships between classes. The data in the binfo can be
accessed by the BINFO_ accessor macros.
- vtable
-
- virtual function table
-
The virtual function table holds information used in virtual function
dispatching. In the compiler, they are usually referred to as vtables,
or vtbls. The first index is not used in the normal way, I believe it
is probably used for the virtual destructor.
- vfield
-
vfields can be thought of as the base information needed to build
vtables. For every vtable that exists for a class, there is a vfield.
See also vtable and virtual function table pointer. When a type is used
as a base class to another type, the virtual function table for the
derived class can be based upon the vtable for the base class, just
extended to include the additional virtual methods declared in the
derived class. The virtual function table from a virtual base class is
never reused in a derived class.
is_normal depends upon this.
- virtual function table pointer
-
These are
FIELD_DECLs that are pointer types that point to
vtables. See also vtable and vfield.
