## Detailed Description

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.

## Member Function Documentation

## ◆ as_reader()

EggReader * EggSingleBase::as_reader | ( |  | ) |
| 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.

Definition at line 41 of file eggSingleBase.cxx.

## ◆ as_writer()

EggWriter * EggSingleBase::as_writer | ( |  | ) |
| virtual

Returns this object as an EggWriter pointer, if it is in fact an EggWriter, 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 EggWriter.
