PredType pred_data

Detailed Description

template<typename IterType, typename PredType>
struct 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.

template<typename IterType, typename PredType>
virtual PredBase* Pred< IterType, PredType >::clone ( ) const [inline, virtual]

Returns a copy of this object as a pointer to the base class.

      variant_filter_iterator::Pred<IterType,PredType> *copy =

template<typename IterType, typename PredType>
virtual PredBase::const_PredBase* Pred< IterType, PredType >::const_clone ( ) const [inline, virtual]

The redefinition of the const_clone function for the Pred class. Notice the strange typename syntax required. Will it compile everywhere?

Important typedef for const_iterators. Notice the weird syntax! Does it compile everywhere?
