[jboss-jira] [JBoss JIRA] Created: (JBRULES-547) Create a specialized "exists" node in reteoo

Create a specialized "exists" node in reteoo -------------------------------------------- Key: JBRULES-547 URL: http://jira.jboss.com/jira/browse/JBRULES-547 Project: JBoss Rules Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Drl Parser/Builder, Reteoo Reporter: Edson Tirelli Assigned To: Edson Tirelli Fix For: 3.1-m2 Currently, "exists" conditional element is implemented as a sequence of 2 "not" nodes. This is suboptimal for performance and adds complexity to the network with specialized constraints and the requirement for a specific RightInputAdapterNode. Also, the currently implementation causes unnecessary work to be performed. For instance, trace the work done in the terminal node in the following example: package org.drools query "2 persons with the same status" p : Person($status : status, $age : age) exists Person(status == $status, age > $age); end So, replace current implementation for a specialized "ExistsNode". -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
