Class ProcessLevelStartEventUndeployContext

java.lang.Object

org.flowable.engine.impl.bpmn.behavior.ProcessLevelStartEventUndeployContext

public class ProcessLevelStartEventUndeployContext
extends Object

Context passed to ProcessLevelStartEventActivityBehavior.undeploy(ProcessLevelStartEventUndeployContext) when a process definition is being superseded by a new version. Carries both the previous (now-superseded) process definition and the new one — most behaviors only need the previous process definition, but the EventRegistry "manual" re-point branch updates subscriptions to point at getNewProcessDefinition().

Behaviors register their obsolete event subscription / timer job handler types via registerObsoleteEventSubscriptionType(String) and registerObsoleteTimerJobHandlerType(String). The deployer issues one mass-delete per unique registered type after the undeploy iteration — fewer DB round-trips than per-start-event deletes, and tighter than the historical fixed Message+Signal+EventRegistry sweep that always ran regardless of which types the previous process definition actually used.

registerObsoleteEventSubscriptionType

public void registerObsoleteEventSubscriptionType(String eventHandlerType)

Registers an event subscription handler type that the deployer should mass-delete for the previous process definition after the undeploy pass. Multiple behaviors registering the same type result in a single DB sweep.

registerObsoleteTimerJobHandlerType

public void registerObsoleteTimerJobHandlerType(String timerJobHandlerType)

Registers a timer job handler type that the deployer should mass-cancel for the previous process definition after the undeploy pass. Multiple behaviors registering the same type result in a single DB sweep.
