Mario Fusco created DROOLS-4632: ----------------------------------- Summary: Optimize single pattern forall statement Key: DROOLS-4632 URL: https://issues.jboss.org/browse/DROOLS-4632 Project: Drools Issue Type: Enhancement Reporter: Mario Fusco Assignee: Mario Fusco At the moment a single pattern forall statement like {code} forall( Type( constraints ) ) {code} it is automatically rewritten as {code} forall( $t : Type() Type( this == $t, constraints ) ) {code} and then implemented with 2 not nodes and join. It would be much faster to rewrite it as {code} not( Type( !constraints ) ) {code} and then evaluate it with one single not node. -- This message was sent by Atlassian Jira (v7.13.8#713008)
