[jboss-jira] [JBoss JIRA] Assigned: (JBRULES-3141) Replace BinaryHeapPriorityQueue Implementation with Java's PriorityBlockingQueue

Replace BinaryHeapPriorityQueue Implementation with Java's PriorityBlockingQueue -------------------------------------------------------------------------------- Key: JBRULES-3141 URL: https://issues.jboss.org/browse/JBRULES-3141 Project: Drools Issue Type: Feature Request Security Level: Public(Everyone can see) Reporter: Brad Davis Assignee: Brad Davis Attachments: BasePriorityQueue.java, BinaryHeapPriorityQueueTest.java Attached is a PriorityQueue implementation I wrote last night to replace our home grown implementation. I think it must have preceded the PriorityBlockingQueue that is already part of Java 5 & 6. BinaryHeapPriorityQueueTest is where I plugged in this implementation. Below are the results first running with our home grown BinaryHeapPriorityQueue, and then with the one I created, BasePriorityQueue. There are numerous other benefits to using this as well, as it will fully implement the java.util.Collections API and therefore cleanup some other code elsewhere in our codebase. The result for 10000 objects inserted and retracted was: BinaryHeapPriortyQueue elapsedEnqueue = 32 elapsedDequeue = 294 BasePriorityQueue elapsedEnqueue = 26 elapsedDequeue = 167
