[jboss-jira] [JBoss JIRA] Assigned: (JBRULES-313) Add halt/run commands

Add halt/run commands --------------------- Key: JBRULES-313 URL: http://jira.jboss.com/jira/browse/JBRULES-313 Project: JBoss Rules Issue Type: Feature Request Security Level: Public(Everyone can see) Environment: any Reporter: Jacek Jarmulak Assigned To: Edson Tirelli Fix For: 4.0.0.MR4 I have made a small modification to WorkingMemory and AbstractWorkingMemory that allows me to pause and the restart rule firing. The change consists of adding a boolean isPaused flag (plus gettter and setter methods) which is then inspected in the while loop of the fireAllRules method as follows public synchronized void fireAllRules(final AgendaFilter agendaFilter) throws FactException { if ( !this.firing ) { try { this.firing = true; while ( !this.isPaused() && this.agenda.fireNextItem( agendaFilter ) ) { ; } } finally { this.firing = false; } } } What is this good for? It lets me stop rule firing from within some rule, e.g. when I want to execute an external call. The rule sets up the call and then calls setPaused(true) on WorkingMemory. Once fireAllRules exits, an external process executes the call, possibly asserting some facts into WorkingMemory and then calls setPaused(false) and calls fireAllRules again. Why not execute the call directly from the rule? Because in my application the execution might take long time, and I want to have an option to move the WorkingMemory out of RAM, possibly moving it to another app server to continue firing after the externall call processing has completed.
