Detailed Description

Abstract class for a rewindable OptIter

Member Function Documentation

virtual const char* OptIterRwd::curr ( void )

pure virtual

curr() returns the current item in the iterator without advancing on to the next item. If we are at the end of items then NULL is returned.

Implements OptIter.

virtual const char* OptIterRwd::curr ( void )

pure virtual

curr() returns the current item in the iterator without advancing on to the next item. If we are at the end of items then NULL is returned.

Implements OptIter.

virtual const char* OptIterRwd::operator() ( void )

pure virtual

operator() returns the current item in the iterator and then advances on to the next item. If we are at the end of items then NULL is returned.

Reimplemented from OptIter.

virtual const char* OptIterRwd::operator() ( void )

pure virtual

operator() returns the current item in the iterator and then advances on to the next item. If we are at the end of items then NULL is returned.
