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.

Member Function Documentation

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

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

Definition at line 244 of file variant_filter_iterator.h.

245  {
246 #ifdef __SUNPRO_CC
247  variant_filter_iterator::Pred<IterType,PredType> *copy =
248  new variant_filter_iterator::Pred<IterType,PredType>(pred_data);
249 #else
252 #endif
254  return copy;
255  }
template<typename IterType, typename PredType>
virtual PredBase::const_PredBase* Pred< IterType, PredType >::const_clone ( ) const

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?
