Class DefaultFlowableEngineAgenda

java.lang.Object

org.flowable.engine.impl.agenda.DefaultFlowableEngineAgenda

All Implemented Interfaces:

Agenda, FlowableEngineAgenda

Direct Known Subclasses:

DebugFlowableEngineAgenda

public class DefaultFlowableEngineAgenda
extends Object
implements FlowableEngineAgenda

For each API call (and thus Command) being executed, a new agenda instance is created. On this agenda, operations are put, which the CommandExecutor will keep executing until all are executed. The agenda also gives easy access to methods to plan new operations when writing ActivityBehavior implementations. During a Command execution, the agenda can always be fetched using Context.getAgenda().
