Constructor Detail

ParallelMultiInstanceActivityBehavior

public ParallelMultiInstanceActivityBehavior()

Method Detail

createInstances

protected void createInstances(ActivityExecution execution,
                               int nrOfInstances)
                        throws Exception

Specified by:

createInstances in class MultiInstanceActivityBehavior

Throws:

Exception

prepareScopeExecution

protected void prepareScopeExecution(ActivityExecution scopeExecution,
                                     int nrOfInstances)

createConcurrentExecution

protected ActivityExecution createConcurrentExecution(ActivityExecution scopeExecution)

concurrentChildExecutionEnded

public void concurrentChildExecutionEnded(ActivityExecution scopeExecution,
                                          ActivityExecution endedExecution)

Description copied from interface: CompositeActivityBehavior

Invoked when an execution is ended within the scope of the composite

Specified by:

concurrentChildExecutionEnded in interface CompositeActivityBehavior

Parameters:

scopeExecution - scope execution for the activity which defined the behavior

endedExecution - the execution which ended

allExecutionsEnded

protected boolean allExecutionsEnded(ActivityExecution scopeExecution,
                                     ActivityExecution endedExecution)

complete

public void complete(ActivityExecution scopeExecution)

Specified by:

complete in interface CompositeActivityBehavior

initializeScope

public List<ActivityExecution> initializeScope(ActivityExecution scopeExecution,
                                               int numberOfInstances)

Description copied from interface: ModificationObserverBehavior

Implement to customize initialization of the scope. Called with the scope execution already created. Implementations may set variables, etc. Implementations should provide return as many executions as there are requested by the argument. Valid number of instances are >= 0.

Specified by:

initializeScope in interface ModificationObserverBehavior

createInnerInstance

public ActivityExecution createInnerInstance(ActivityExecution scopeExecution)

Description copied from interface: ModificationObserverBehavior

Returns an execution that can be used to execute an activity within that scope. May reorganize other executions in that scope (e.g. implement to override the default pruning behavior).

Specified by:

createInnerInstance in interface ModificationObserverBehavior

destroyInnerInstance

public void destroyInnerInstance(ActivityExecution concurrentExecution)

Description copied from interface: ModificationObserverBehavior

implement to destroy an execution in this scope and handle the scope's reorganization (e.g. implement to override the default pruning behavior). The argument execution is not yet removed.

Specified by:

destroyInnerInstance in interface ModificationObserverBehavior

migrateScope

public void migrateScope(ActivityExecution scopeExecution)

Description copied from interface: MigrationObserverBehavior

Implement to perform activity-specific migration behavior that is not covered by the regular migration procedure. Called after the scope execution and any ancestor executions have been migrated to their target activities and process definition.

Specified by:

migrateScope in interface MigrationObserverBehavior

onParseMigratingInstance

public void onParseMigratingInstance(MigratingInstanceParseContext parseContext,
                                     MigratingActivityInstance migratingInstance)

Description copied from interface: MigrationObserverBehavior

Callback to implement behavior specific parsing (e.g. adding additional dependent entities).

Specified by:

onParseMigratingInstance in interface MigrationObserverBehavior
