Member Function Documentation

busy()

template<class T >

virtual bool iterator_rep< T >::busy ( )

pure virtual

Returns whether the iterator has another element.

Returns

True if the iterator has another element, false otherwise.

Implemented in hashset_iterator_rep< T >, and hashmap_iterator_rep< T, U >.

next()

template<class T >

virtual T iterator_rep< T >::next ( )

pure virtual

Returns the current element of the iterator, and move the iterator forward.

Returns

The current element of the iterator.

Implemented in hashset_iterator_rep< T >, and hashmap_iterator_rep< T, U >.

current()

template<class T >

virtual T iterator_rep< T >::current ( )

pure virtual

Returns the current element of the iterator.

Returns

The current element of the iterator.

Implemented in hashset_iterator_rep< T >, and hashmap_iterator_rep< T, U >.

increase()

template<class T >

virtual void iterator_rep< T >::increase ( )

pure virtual

Increase the iterator.

Implemented in hashset_iterator_rep< T >, and hashmap_iterator_rep< T, U >.

remains()

template<class T >

int iterator_rep< T >::remains ( )

virtual

Returns the number of elements remaining in the iterator.

Returns

The number of elements remaining in the iterator.
