Class DefaultJobExecutor

java.lang.Object

org.activiti.engine.impl.jobexecutor.JobExecutor

org.activiti.engine.impl.jobexecutor.DefaultJobExecutor

Direct Known Subclasses:

ManagedJobExecutor

public class DefaultJobExecutor
extends JobExecutor

This is a simple implementation of the JobExecutor using self-managed threads for performing background work.

This implementation uses a ThreadPoolExecutor backed by a queue to which work is submitted.

NOTE: use this class in environments in which self-management of threads is permitted. Consider using a different thread-management strategy in J(2)EE-Environments.
