Detailed Description

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
class RWTValMultiMapConstIterator< K, T, C, A >

Deprecated:
As of SourcePro 12.5, use RWTValMultiMap::const_iterator to iterate over the elements in this collection.

RWTValMultiMapConstIterator provides a const iterator for RWTValMultiMap. A const iterator prohibits any changes to the collection it iterates over.

The order of iteration for an RWTValMultiMap is dependent upon the comparator object as applied to the keys of the stored associations.

The current item referenced by this iterator is undefined after construction or after a call to reset(). The iterator becomes valid after being advanced with either a pre-increment or operator()().

For both operator++() and operator()(), iterating past the last element returns a value equivalent to boolean false. Continued increments return a value equivalent to false until reset() is called.

The value type must have operator== and operator< defined. This requirement is imposed by the C++ Standard Library.

Constructor & Destructor Documentation

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
RWTValMultiMapConstIterator< K, T, C, A >::RWTValMultiMapConstIterator ( const RWTValMultiMap< K, T, C, A > &  m)
inline

Creates a const iterator for the multi-map m. The iterator begins in an undefined state and must be advanced before the first association is accessible.

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
RWTValMultiMapConstIterator< K, T, C, A >::RWTValMultiMapConstIterator ( const RWTValMultiMapIterator< K, T, C, A > &  itr)
inline

Creates a const iterator from the iterator itr. The const iterator begins in an undefined state and must be advanced before the first association is accessible.

Member Function Documentation

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
const RWTValMultiMap<K, T, C, A>* RWTValMultiMapConstIterator< K, T, C, A >::container ( ) const
inline

Returns a pointer to the collection being iterated over.

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
const K& RWTValMultiMapConstIterator< K, T, C, A >::key ( ) const
inline

Returns the key portion of the association currently referenced by self.

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
bool RWTValMultiMapConstIterator< K, T, C, A >::operator() ( void  )
inline

Advances self to the next element and returns true. Returns false if the iterator has advanced past the last element in the collection.

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
bool RWTValMultiMapConstIterator< K, T, C, A >::operator++ ( )
inline

Advances self to the next element. If the iterator has been reset or just created, self now references the first element. If, before iteration, self referenced the last association in the multi-map, self now references an undefined value and false is returned. Otherwise, returns true.

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
void RWTValMultiMapConstIterator< K, T, C, A >::reset ( void  )
inline

Resets the iterator so that after being advanced, it references the first element of the collection.

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
void RWTValMultiMapConstIterator< K, T, C, A >::reset ( const RWTValMultiMap< K, T, C, A > &  h)
inline

Resets the iterator so that after being advanced, it references the first element of the collection h.

template<class K, class T, class C = std::less<K>, class A = std::allocator< std::pair<K const, T> >>
const T& RWTValMultiMapConstIterator< K, T, C, A >::value ( void  ) const
inline

Returns the value portion of the association referenced by self.
