Constructor Summary

ScopeUtil()

Method Summary

static void	createEventScopeExecution(ExecutionEntity execution) creates an event scope for the given execution: create a new event scope execution under the parent of the given execution and move all event subscriptions to that execution.
static ActivityImpl	findInParentScopesByBehaviorType(ActivityImpl activity, Class<? extends ActivityBehavior> behaviorType)
static ActivityExecution	findScopeExecution(ActivityExecution execution) Find the next scope execution in the parent execution hierarchy That method works different than findScopeExecutionForScope(org.camunda.bpm.engine.impl.persistence.entity.ExecutionEntity, org.camunda.bpm.engine.impl.pvm.PvmScope) which returns the most outer scope execution.
static ExecutionEntity	findScopeExecutionForScope(ExecutionEntity execution, PvmScope scopeActivity) returns the top-most execution sitting in an activity part of the scope defined by 'scopeActivitiy'.
static void	throwCompensationEvent(List<CompensateEventSubscriptionEntity> eventSubscriptions, ActivityExecution execution, boolean async) we create a separate execution for each compensation handler invocation.

Method Detail

findScopeExecution

public static ActivityExecution findScopeExecution(ActivityExecution execution)

Find the next scope execution in the parent execution hierarchy That method works different than findScopeExecutionForScope(org.camunda.bpm.engine.impl.persistence.entity.ExecutionEntity, org.camunda.bpm.engine.impl.pvm.PvmScope) which returns the most outer scope execution.

Parameters:

execution - the execution from which to start the search

Returns:

the next scope execution in the parent execution hierarchy

findScopeExecutionForScope

public static ExecutionEntity findScopeExecutionForScope(ExecutionEntity execution,
                                                         PvmScope scopeActivity)

returns the top-most execution sitting in an activity part of the scope defined by 'scopeActivitiy'.

findInParentScopesByBehaviorType

public static ActivityImpl findInParentScopesByBehaviorType(ActivityImpl activity,
                                                            Class<? extends ActivityBehavior> behaviorType)

throwCompensationEvent

public static void throwCompensationEvent(List<CompensateEventSubscriptionEntity> eventSubscriptions,
                                          ActivityExecution execution,
                                          boolean async)

we create a separate execution for each compensation handler invocation.

createEventScopeExecution

public static void createEventScopeExecution(ExecutionEntity execution)

creates an event scope for the given execution: create a new event scope execution under the parent of the given execution and move all event subscriptions to that execution. this allows us to "remember" the event subscriptions after finishing a scope
