Method Detail

setOperationForTransition

public static void setOperationForTransition(Transition transition,
                                             Operation operation)

Set derived property operation for transition. Operation is mapped to first trigger call event operation. If transition does not own trigger, new one is created. If trigger does not reference CallEvent or old even is referenced by other elements, new CallEvent is created.

Parameters:

transition - the given transition

operation - the given operation

setSignalForTransition

public static void setSignalForTransition(Transition transition,
                                          Signal signal)

Set derived property signal for transition. Signal is mapped to first trigger signal event signal. If transition does not own trigger, new one is created. If trigger does not reference SignalEvent or old even is referenced by other elements, new SignalEvent is created.

Parameters:

transition - the given transition

signal - the given signal

getOperationForTransition

@CheckForNull
public static Operation getOperationForTransition(Transition transition)

Returns an operation of given transition. Operation is taken from trigger call event.

Parameters:

transition - the given transition

Returns:

an operation of given transition

getSignalForTransition

@CheckForNull
public static Signal getSignalForTransition(Transition transition)

Returns a signal of given transition. Signal is taken from trigger signal event.

Parameters:

transition - the given transition

Returns:

a signal of given transition

isSignalEvent

public static boolean isSignalEvent(Transition transition)

Check if event of given transition is SignalEvent

Parameters:

transition - transition

Returns:

true if event is SignalEvent

isCallEvent

public static boolean isCallEvent(Transition transition)

Check if event of given transition is CallEvent

Parameters:

transition - transition

Returns:

true if event is CallEvent

getOperationsForTransition

public static java.util.Collection<Operation> getOperationsForTransition(Classifier classifier)

Collects operations from given classifiers, base classifiers and provided interfaces of given classifiers. Current implementation uses InteractionHelper.getOperationsForCallAction(classifier)

Parameters:

classifier - classifier

Returns:

operations

See Also:

InteractionHelper.getOperationsForCallAction(com.nomagic.uml2.ext.magicdraw.classes.mdkernel.Classifier)

getClassifierForTransition

@CheckForNull
public static Classifier getClassifierForTransition(Transition transition)

Returns the classifier as context for given transition. If transition is in protocol state machine, ProtocolStateMachine.Interface can be returned.

Parameters:

transition - transition

Returns:

classifier

getStateMachineContext

@CheckForNull
public static Classifier getStateMachineContext(StateMachine machine)

Returns the context of the state machine.

Parameters:

machine - - state machine.

Returns:

context of the state machine.

disposeTriggers

public static void disposeTriggers(java.util.List<Trigger> triggers)

Disposes given collection of triggers and referenced by them events

Parameters:

triggers - triggers

disposeEvent

public static void disposeEvent(@CheckForNull
                                Event event)

Disposes event if it is not used any more by other elements in the model.

Parameters:

event - event
