public MigratingActivityInstance(ActivityInstance activityInstance,
                                 MigrationInstruction migrationInstruction,
                                 ScopeImpl sourceScope,

Method Detail

detachState

public void detachState()

Description copied from interface: MigratingInstance

Detach this instance's state from the execution tree

Specified by:

detachState in interface MigratingInstance

attachState

public void attachState(ExecutionEntity newScopeExecution)

Description copied from interface: MigratingInstance

Restore this instance's state to the execution tree. Restoration should restore the state that was detached before (i.e. the source process definition state)

Specified by:

attachState 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:

migrateDependentEntities in interface MigratingInstance

resolveRepresentativeExecution

public ExecutionEntity resolveRepresentativeExecution()

addMigratingDependentInstance

public void addMigratingDependentInstance(MigratingInstance migratingInstance)

addRemovingDependentInstance

public void addRemovingDependentInstance(RemovingInstance removingInstance)

addEmergingDependentInstance

public void addEmergingDependentInstance(EmergingInstance emergingInstance)

getActivityInstance

public ActivityInstance getActivityInstance()

getSourceScope

public ScopeImpl getSourceScope()

getTargetScope

public ScopeImpl getTargetScope()

getChildren

public Set<MigratingActivityInstance> getChildren()

getParent

public MigratingActivityInstance getParent()

setParent

public void setParent(MigratingActivityInstance parentInstance)

getMigrationInstruction

public MigrationInstruction getMigrationInstruction()

migrates

public boolean migrates()

removeUnmappedDependentInstances

public void removeUnmappedDependentInstances()

remove

public void remove()

Description copied from interface: RemovingInstance

Remove this instance from the process instance.

Specified by:

remove in interface RemovingInstance

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
