Detailed Description

Abstract class to iterate through options/arguments

Member Function Documentation

virtual const char* OptIter::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.

Implemented in OptIstreamIter, OptStrTokIter, OptArgvIter, and OptIterRwd.

const char * OptIter::operator() ( void  )

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 in OptIstreamIter, OptStrTokIter, OptArgvIter, and OptIterRwd.
