Method Detail

getJobEntity

public JobEntity getJobEntity()

addMigratingDependentInstance

public void addMigratingDependentInstance(MigratingInstance migratingInstance)

isDetached

public boolean isDetached()

Specified by:

isDetached in interface MigratingInstance

detachState

public void detachState()

Description copied from interface: MigratingInstance

Detach this instance's state from its owning instance and the execution tree

Specified by:

detachState in interface MigratingInstance

attachState

public void attachState(MigratingScopeInstance newOwningInstance)

Description copied from interface: MigratingInstance

Restore this instance's state as a subordinate to the given activity instance (e.g. in the execution tree). Restoration should restore the state that was detached before.

Migrate state from the source process definition to the target process definition.

Specified by:

migrateState in interface MigratingInstance

migrateDependentEntities

public void migrateDependentEntities()

Description copied from interface: MigratingInstance

Migrate instances that are aggregated by this instance (e.g. an activity instance aggregates task instances).

Specified by:
