Member Function Documentation

virtual bool jem::util::SequenceEnumerator::atBegin ( ) const

pure virtual

virtual void jem::util::SequenceEnumerator::toNext ( )

virtual

Advances this enumerator to the next object in the collection, or to the end object if there is no next object. This function may not be called if this enumerator already points to the end object.
