All Implemented Interfaces:

Serializable, PvmProcessElement, PvmScope

Direct Known Subclasses:

ActivityImpl, ProcessDefinitionImpl

public abstract class ScopeImpl
extends CoreActivity
implements PvmScope

A Bpmn scope. The scope has references to two lists of activities: - the flow activities (activities for which the flow scope is this scope - event listener activities (activities for which the event scope is this scope.

Field Detail

isSubProcessScope

protected boolean isSubProcessScope

flowActivities

protected List<ActivityImpl> flowActivities

The activities for which the flow scope is this scope

namedFlowActivities

protected Map<String,ActivityImpl> namedFlowActivities

processDefinition

protected ProcessDefinitionImpl processDefinition

BACKLOG

protected final Map<String,ScopeImpl.BacklogErrorCallback> BACKLOG

The key identifies the activity which is referenced but not read yet. The value is the error callback, which is called if the activity is not read till the end of parsing.

Method Detail

findActivity

public ActivityImpl findActivity(String activityId)

Description copied from class: CoreActivity

searches for the activity recursively

Specified by:

findActivity in interface PvmScope

Overrides:

findActivity in class CoreActivity

Parameters:

activityId - the id of the activity to find.

Returns:

the activity or null

findTransition

public TransitionImpl findTransition(String transitionId)

Description copied from interface: PvmScope

Recursively finds a transition.

Specified by:

findTransition in interface PvmScope

Parameters:

transitionId - the transiton to find

Returns:

the transition or null

findActivityAtLevelOfSubprocess

public ActivityImpl findActivityAtLevelOfSubprocess(String activityId)

Description copied from interface: PvmScope

Finds an activity at the same level of subprocess.

Specified by:

findActivityAtLevelOfSubprocess in interface PvmScope

Parameters:

activityId - the id of the activity to find.

Returns:

the activity or null

getChildActivity

public ActivityImpl getChildActivity(String activityId)

searches for the activity locally

Specified by:

getChildActivity in class CoreActivity

getBacklogErrorCallbacks

public Collection<ScopeImpl.BacklogErrorCallback> getBacklogErrorCallbacks()

Returns the backlog error callback's.

Returns:

the callback's

isBacklogEmpty

public boolean isBacklogEmpty()

Returns true if the backlog is empty.

Returns:

true if empty, false otherwise

addToBacklog

public void addToBacklog(String activityRef,
                ScopeImpl.BacklogErrorCallback callback)

Add's the given activity reference and the error callback to the backlog.

Parameters:

activityRef - the activity reference which is not read until now

callback - the error callback which should called if activity will not be read

createActivity

public ActivityImpl createActivity(String activityId)

Specified by:

createActivity in class CoreActivity

isAncestorFlowScopeOf

public boolean isAncestorFlowScopeOf(ScopeImpl other)

contains

public boolean contains(ActivityImpl activity)

getExecutionListeners

@Deprecated
public List<ExecutionListener> getExecutionListeners(String eventName)

Deprecated.

addExecutionListener

@Deprecated
public void addExecutionListener(String eventName,
                                   ExecutionListener executionListener)

Deprecated.

addExecutionListener

@Deprecated
public void addExecutionListener(String eventName,
                                   ExecutionListener executionListener,
                                   int index)

Deprecated.

getExecutionListeners

@Deprecated
public Map<String,List<ExecutionListener>> getExecutionListeners()

Deprecated.

getActivities

public List<ActivityImpl> getActivities()

Description copied from interface: PvmScope

Returns the flow activities of this scope. This is the list of activities for which this scope is the flow scope.

Specified by:

getActivities in interface PvmScope

Specified by:

getActivities in class CoreActivity

Returns:

the list of flow activities for this scope.

public ProcessDefinitionImpl getProcessDefinition()

Description copied from interface: PvmProcessElement

The process definition scope, root of the scope hierarchy.

Specified by:

getProcessDefinition in interface PvmProcessElement

Returns:
