Detailed Description

template<int _NAME_COUNT, IteratorType T>
struct pdfobjects::RejectingPdfOperatorIterator< _NAME_COUNT, T >

Generic iterator that rejects set of operators.

This is a very generic class which iterates over all but specified operators. Use this class when a special iterator is desired.

Member Function Documentation

template<int _NAME_COUNT, IteratorType T>
virtual bool pdfobjects::RejectingPdfOperatorIterator< _NAME_COUNT, T >::validItem (  )  const [inline, virtual]

In the base iterator, loop through all objects. We can overload this function to be able to iterate only over specific items.

Returns:
True if the item is supported by this type of iterator, false otherwise.

Reimplemented from iterator::DoubleListIterator< Item >.
