Detailed Description

This abstract class defines a isEos() operation that is intended to be used Input and Output streams.

Since InputOutput streams are supported we end up with 2 isEos() methods when the InputOutput class inherits from Input and Output interfaces. This causes basically a 'diamond' problem. By making the isEof() it owns interface and a parent class - we can use the 'virtual mechanism' in C++ to ensure that for InputOutput classes there is one and only one isEos() method.
