Detailed Description

 

template<class Predicate, class Type, class ReferenceType = Type&, class PointerType = Type*>template<typename IterType, typename PredType> struct variant_filter_iterator< Predicate, Type, ReferenceType, PointerType >::Pred< IterType, PredType >

The actual predicate is held as a template parameter here. There are two template arguments here, one for the actual type of the predicate and one for the iterator type.
