Detailed Description

template<typename BaseIterator>
class FilteredIterator< BaseIterator >::PredicateBase

Base class to encapsulate a predicate object. Since predicates can be of different types and we do not want to code these types into the template parameter list of the filtered iterator class, we use a base class with an abstract function and templatized derived classes that implement the use of actual predicate types through the virtual function.

Constructor & Destructor Documentation

◆ ~PredicateBase()

template<typename BaseIterator >
virtual FilteredIterator< BaseIterator >::PredicateBase::~PredicateBase ( )

Mark the destructor virtual to allow destruction through pointers to the base class.

Member Function Documentation

◆ operator()()

template<typename BaseIterator >
virtual bool FilteredIterator< BaseIterator >::PredicateBase::operator() ( const BaseIterator bi) const
pure virtual

Abstract function which in derived classes denotes the evaluation of the predicate on the given iterator.

Implemented in FilteredIterator< BaseIterator >::PredicateTemplate< Predicate >.

◆ clone()

template<typename BaseIterator >
virtual std::unique_ptr< PredicateBase > FilteredIterator< BaseIterator >::PredicateBase::clone ( ) const
pure virtual

Generate a copy of this object, i.e. of the actual type of this pointer.

Implemented in FilteredIterator< BaseIterator >::PredicateTemplate< Predicate >.
