question: private boolean hasOtherQueuedParentNode ( Lop tmpNode , ArrayList < Lop > queuedNodes , Lop node ) { if ( queuedNodes . isEmpty ( ) ) return false ; boolean [ ] nodeMarked = node . get_reachable ( ) ; boolean [ ] tmpMarked = tmpNode . get_reachable ( ) ; long nodeid = IDMap . get ( node . getID ( ) ) ; long tmpid = IDMap . get ( tmpNode . getID ( ) ) ; for ( Lop qnode : queuedNodes ) { int id = IDMap . get ( qnode . getID ( ) ) ; if ( ( id != nodeid && nodeMarked [ id ] ) && ( id != tmpid && tmpMarked [ id ] ) ) return true ; } return false ; }
target:  Method to check if there is a queued node that is a parent of both tmpNode and node
