question: protected void clearTemps_and_EdgesFromNodes ( ) { int curSize = m_nodes . size ( ) ; for ( int i = origNodesSize ; i < curSize ; i ++ ) { m_nodes . remove ( origNodesSize ) ; } for ( int j = 0 ; j < m_nodes . size ( ) ; j ++ ) { m_nodes . get ( j ) . edges = null ; } nodeLevels = null ; }
target:  This method removes the temporary nodes that were added to fill in the gaps, and removes all edges from all nodes in their edges[][] array
