Constructor Detail

ActivityImpl

public ActivityImpl(String id,
                    ProcessDefinitionImpl processDefinition)

Method Detail

createOutgoingTransition

public TransitionImpl createOutgoingTransition()

createOutgoingTransition

public TransitionImpl createOutgoingTransition(String transitionId)

findOutgoingTransition

public TransitionImpl findOutgoingTransition(String transitionId)

Description copied from interface: PvmActivity

Finds and returns an outgoing sequence flow (transition) by it's id.

Specified by:

findOutgoingTransition in interface PvmActivity

Parameters:

transitionId - the id of the transition to find

Returns:

the transition or null in case it cannot be found

toString

public String toString()

Overrides:

toString in class CoreActivity

setOutgoingTransitions

protected void setOutgoingTransitions(List<TransitionImpl> outgoingTransitions)

setIncomingTransitions

protected void setIncomingTransitions(List<TransitionImpl> incomingTransitions)

getOutgoingTransitions

public List<PvmTransition> getOutgoingTransitions()

Specified by:

getOutgoingTransitions in interface PvmActivity

Returns:

the list of outgoing sequence flows (transitions)

getActivityBehavior

public ActivityBehavior getActivityBehavior()

Description copied from interface: PvmActivity

The inner behavior of an activity. The inner behavior is the logic which is executed after the start listeners have been executed. In case the activity is scope, a new execution will be created

Specified by:

getActivityBehavior in interface PvmActivity

Specified by:

getActivityBehavior in class CoreActivity

Returns:

the inner behavior of the activity

setActivityBehavior

public void setActivityBehavior(ActivityBehavior activityBehavior)

getActivityStartBehavior

public ActivityStartBehavior getActivityStartBehavior()

Description copied from interface: PvmActivity

The start behavior of an activity. The start behavior is executed before the start listeners of the activity are executed.

Specified by:

getActivityStartBehavior in interface PvmActivity

Returns:

the start behavior of an activity.

setActivityStartBehavior

public void setActivityStartBehavior(ActivityStartBehavior activityStartBehavior)

getIncomingTransitions

public List<PvmTransition> getIncomingTransitions()

Specified by:

getIncomingTransitions in interface PvmActivity

Returns:

the list of incoming sequence flows (transitions)

isScope

public boolean isScope()

Description copied from interface: PvmScope

Indicates whether this is a local scope for variables and events if true, there will _always_ be a scope execution created for it.

Note: the fact that this is a scope does not mean that it is also a sub process scope.

Specified by:

isScope in interface PvmScope

setScope

public void setScope(boolean isScope)

isAsyncBefore

public boolean isAsyncBefore()

Description copied from interface: PvmActivity

Indicates whether the activity is executed asynchronously. This can be done after the activity start behavior and before the start listeners are invoked.

Specified by:

isAsyncBefore in interface PvmActivity

Returns:

true if the activity is executed asynchronously.

setAsyncBefore

public void setAsyncBefore(boolean isAsyncBefore)

setAsyncBefore

public void setAsyncBefore(boolean isAsyncBefore,
                           boolean exclusive)

isAsyncAfter

public boolean isAsyncAfter()

Description copied from interface: PvmActivity

Indicates whether execution after this execution should continue asynchronously. This can be done after the end listeners are invoked.

Specified by:

isAsyncAfter in interface PvmActivity

Returns:

true if execution after this activity continues asynchronously.

setAsyncAfter

public void setAsyncAfter(boolean isAsyncAfter)

setAsyncAfter

public void setAsyncAfter(boolean isAsyncAfter,
                          boolean exclusive)

getActivityId

public String getActivityId()

getFlowScope

public ScopeImpl getFlowScope()

Description copied from interface: PvmScope

The flow scope of the activity. The scope in which the activity itself is executed.

Note: in order to ensure backwards compatible behavior, a flow scope is not necessarily a a scope. Example: event sub processes.

Specified by:

getFlowScope in interface PvmScope

getEventScope

public ScopeImpl getEventScope()

Description copied from interface: PvmScope

The event scope for an activity is the scope in which the activity listens for events. This may or may not be the flow scope.. Consider: boundary events have a different event scope than flow scope.

The event scope is always a scope.

Specified by:

getEventScope in interface PvmScope

Returns:

the event scope of the activity

setEventScope

public void setEventScope(ScopeImpl eventScope)

getLevelOfSubprocessScope

public PvmScope getLevelOfSubprocessScope()

Description copied from interface: PvmScope

The "level of subprocess scope" as defined in bpmn: this is the subprocess containing the activity. Usually this is the same as the flow scope, instead if the activity is multi instance: in that case the activity is nested inside a mutli instance body but "at the same level of subprocess" as other activities which are siblings to the mi-body.

Specified by:

getLevelOfSubprocessScope in interface PvmScope

Returns:

the level of subprocess scope as defined in bpmn
