Method Detail

getSupportedEventTypes

public abstract java.lang.String[] getSupportedEventTypes()

indicative set of event types supported by this graph element. this is currently only used by the process designer to know which event types to show on a given graph element. in process definitions and at runtime, there are no contstraints on the event-types.

---

getEvents

public java.util.Map getEvents()

gets the events, keyd by eventType (java.lang.String).

---

hasEvents

public boolean hasEvents()

---

getEvent

public Event getEvent(java.lang.String eventType)

---

hasEvent

public boolean hasEvent(java.lang.String eventType)

---

addEvent

public Event addEvent(Event event)

---

removeEvent

public Event removeEvent(Event event)

---

getExceptionHandlers

public java.util.List getExceptionHandlers()

is the list of exception handlers associated to this graph element.

---

addExceptionHandler

public ExceptionHandler addExceptionHandler(ExceptionHandler exceptionHandler)

---

removeExceptionHandler

public void removeExceptionHandler(ExceptionHandler exceptionHandler)

---

reorderExceptionHandler

public void reorderExceptionHandler(int oldIndex,
                                    int newIndex)

---

fireEvent

public void fireEvent(java.lang.String eventType,
                      ExecutionContext executionContext)

---

                                  ExecutionContext executionContext)

---

executeAction

public void executeAction(Action action,
                          ExecutionContext executionContext)

---

raiseException

public void raiseException(java.lang.Throwable exception,
                           ExecutionContext executionContext)
                    throws DelegationException

throws an ActionException if no applicable exception handler is found. An ExceptionHandler is searched for in this graph element and then recursively up the parent hierarchy. If an exception handler is found, it is applied. If the exception handler does not throw an exception, the exception is considered handled. Otherwise the search for an applicable exception handler continues where it left of with the newly thrown exception.

Throws:

DelegationException

---

findExceptionHandler

protected ExceptionHandler findExceptionHandler(java.lang.Throwable exception)

---

getParent

public GraphElement getParent()

---

getParents

public java.util.List getParents()

Returns:
