This specialization of EggBase is intended for programs that read and/or write a single egg file.
(See EggMultiBase for programs that operate on multiple egg files at once.)
This is just a base class; see EggReader, EggWriter, or EggFilter according to your particular I/O needs.

virtual |
Returns this object as an EggReader pointer, if it is in fact an EggReader, or NULL if it is not.
This is intended to work around the C++ limitation that prevents downcasts past virtual inheritance. Since both EggReader and EggWriter inherit virtually from EggSingleBase, we need functions like this to downcast to the appropriate pointer.
Reimplemented in EggReader.
