Method Detail

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:

migrateDependentEntities in interface 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(MigratingActivityInstance owningInstance)

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.

Specified by:

attachState in interface MigratingInstance

attachState

public void attachState(MigratingTransitionInstance targetTranisitionInstance)

Description copied from interface: MigratingInstance

Specified by:

attachState in interface MigratingInstance

migrateState

public void migrateState()

Description copied from interface: MigratingInstance

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

Specified by:

migrateState in interface MigratingInstance

getId
