Class AbstractLongRunningListener

java.lang.Object

org.nuxeo.ecm.core.event.impl.AbstractLongRunningListener

All Implemented Interfaces:

PostCommitEventListener, PostCommitFilteringEventListener

public abstract class AbstractLongRunningListener
extends Object
implements PostCommitFilteringEventListener

Abstract class that helps building an Asynchronous listeners that will handle a long running process.

By default, PostCommitEventListener are executed in a Work that will take care of starting/comitting the transaction.

If the listener requires a long processing this will create long transactions that are not good. To avoid this behavior, this base class split the processing in 3 steps :

• pre processing : transactional first step
• long running : long running processing that should not require transactional resources
• post processing : transactional final step

To manage sharing between the 3 steps, a simple Map is provided.
