Description
Class RWCollection is an abstract base class for the Smalltalk-like collection classes. The class
contains virtual functions for inserting and retrieving pointers to RWCollectable objects into the
collection classes. Virtual functions are also provided for storing and reading the collections to
files and streams. Collections that inherit this base class will typically redefine one or more of
these functions.
In the documentation below, pure virtual functions are indicated by "= 0" in their declaration.
These functions must be defined in derived classes. For these functions the description is
intended to be generic -- all inheriting collection classes generally follow the described pattern.
Exceptions are noted in the documentation for the particular class.
For many other functions, a suitable definition is provided by RWCollection and a deriving
class may not need to redefine the function. Examples are contains() or restoreGuts().
