Class StreamWorkManager

java.lang.Object

org.nuxeo.runtime.model.DefaultComponent

org.nuxeo.ecm.core.work.WorkManagerImpl

org.nuxeo.ecm.core.work.StreamWorkManager

All Implemented Interfaces:

WorkManager, Adaptable, Component, Extensible, TimestampedService

public class StreamWorkManager
extends WorkManagerImpl

WorkManager impl that appends works into a Log. Works are therefore immutable (no state update) and can not be listed for performance reason.

Since:

9.3
