question: this map checks if there is an itemset of size i with its key value to true concode_field_sep Map<Itemset,Integer> mapPredSupp concode_elem_sep List<List<Itemset>> levels concode_elem_sep Map<Itemset,Boolean> mapKey concode_field_sep placeholderType placeHolder
target: boolean function ( int arg0 ) { for ( Itemset loc0 : levels . get ( arg0 ) ) { if ( mapKey . get ( loc0 ) == true ) { return true ; } } return false ; }
