Member Function Documentation

current()

template<class T >

virtual const T& ConstIterator< T >::current ( ) const

pure virtual

Get the current item read-only.

Returns

Reference to the next item.

hasCurrent()

template<class T >

virtual bool ConstIterator< T >::hasCurrent ( ) const

pure virtual

Check if there is a current item.

Returns

True if the iterator has a current item, false otherwise.

hasNext()

template<class T >

virtual bool ConstIterator< T >::hasNext ( ) const

pure virtual

Check if there is more to iterate.

Returns

true if more items, false if not.

next()

template<class T >

virtual const T& ConstIterator< T >::next ( )

pure virtual

Fetch the next item.

This function first fetches the next item and then updates the current item pointer to that item.

Returns

Reference to the next item.

Implemented in ConstHashIterator< K, V >.

operator++()

template<class T >

virtual void ConstIterator< T >::operator++ ( int  num )

pure virtual

Increment operator.

This function first increment the current item and then updates the next item pointer.

Parameters

num

Ignored

Implemented in ConstHashIterator< K, V >.

reset()

template<class T >

virtual void ConstIterator< T >::reset ( )

pure virtual

Restart iteration from the beginning.

Implemented in ConstHashIterator< K, V >.
