Class TaskRunnerFactory

java.lang.Object
  org.apache.activemq.thread.TaskRunnerFactory

All Implemented Interfaces:

Executor

public class TaskRunnerFactory
extends Object
implements Executor

Manages the thread pool for long running tasks. Long running tasks are not always active but when they are active, they may need a few iterations of processing for them to become idle. The manager ensures that each task is processes but that no one task overtakes the system. This is kinda like cooperative multitasking.
