详细描述

template<typename IterType, typename PredType>
struct variant_filter_iterator< Predicate, Type, ReferenceType, PointerType, ConstType, ConstReferenceType, ConstPointerType >::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.
