Class DefaultConcurrentTaskModificationPolicy

java.lang.Object

cn.boboweike.carrot.server.configuration.DefaultConcurrentTaskModificationPolicy

All Implemented Interfaces:

ConcurrentTaskModificationPolicy

public class DefaultConcurrentTaskModificationPolicy
extends Object
implements ConcurrentTaskModificationPolicy

Default implementation of ConcurrentTaskModificationPolicy.

If Tasks are deleted, the DefaultConcurrentTaskModificationPolicy will resolve the concurrent task modification by stopping the processing of the task. For other concurrent modifications, the DefaultConcurrentTaskModificationPolicy will throw UnresolvableConcurrentTaskModificationException as these may point to programming errors (Carrot was conceived with the idea that once a task is being processed, it should not be modified anymore).
