question: public Tuple [ ] clearInternal ( ) { Tuple [ ] t = new Tuple [ getTupleCount ( ) ] ; Iterator iter = tuples ( ) ; for ( int i = 0 ; iter . hasNext ( ) ; ++ i ) { t [ i ] = ( Tuple ) iter . next ( ) ; } m_tuples . clear ( ) ; return t ; }
target:  Clear the internal state without firing a notification.
