Class DefaultConcurrentTaskModificationResolver

java.lang.Object

cn.boboweike.carrot.server.concurrent.DefaultConcurrentTaskModificationResolver

All Implemented Interfaces:

ConcurrentTaskModificationResolver

public class DefaultConcurrentTaskModificationResolver
extends Object
implements ConcurrentTaskModificationResolver

Default implementation of ConcurrentTaskModificationResolver.

If Tasks are deleted, the DefaultConcurrentTaskModificationResolver will resolve the concurrent task modification by stopping the processing of the task. For other concurrent modifications, the DefaultConcurrentTaskModificationResolver 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).
