Detailed Description

template<typename HostType>
class NCollection_ForwardRangeIterator< HostType >

STL input iterator that wraps an OCCT More()/Next() iterator.

Holds a non-owning pointer to the host iterator/explorer. The host must outlive this iterator (guaranteed by range-for semantics).

Template Parameters

HostType OCCT iterator/explorer with More(), Next(), and a value accessor.
