template<class T>

virtual bool JLANG::JObjectIterator< T >::hasNext ( )

pure virtualinherited

Check availability of next element.

Returns: true if the iteration has more elements; else false

template<class T>

virtual const pointer_type& JLANG::JObjectIterator< T >::next ( )

pure virtualinherited

Get next element.

Returns: pointer to element

template<class T>

virtual skip_type JLANG::JObjectIterator< T >::skip ( const skip_type ns )

inlinevirtualinherited

Skip items.

Parameters

ns	number of items to skip

Returns: number of items skipped
