Initializes a new instance of the ProgramStateMachineModel class.

UnifiedAutomation.UaServer.ProgramStateMachineModel.ProgramStateMachineModel	(	ProgramStateMachineModel	template,
		DummyArgument	dummy = `null`
	)

Member Function Documentation

static LocalizedText UnifiedAutomation.UaServer.ProgramStateMachineModel.GetLocalizedText ( State state )

static

Retrieves a LocalizedText for the given state value.

Parameters

state The state to get the text.

Returns: The text.

static LocalizedText UnifiedAutomation.UaServer.ProgramStateMachineModel.GetLocalizedText ( Transition transition )

static

Retrieves a LocalizedText for the given transition value.

Parameters

transition The transition to get the text.

Returns: The transition.

static QualifiedName UnifiedAutomation.UaServer.ProgramStateMachineModel.GetName ( State state )

static

Retrieves a QualifiedName for the given state value.

Parameters

state The state to get the name.

Returns: The name.

static QualifiedName UnifiedAutomation.UaServer.ProgramStateMachineModel.GetName ( Transition transition )

static

Retrieves a QualifiedName for the given transition value.

Parameters

transition The transition to get the name.

Returns: The name.

static NodeId UnifiedAutomation.UaServer.ProgramStateMachineModel.GetNodeId ( State state )

static

Retrieves the NodeId for the given state value.

Parameters

state The state to get the NodeId.

Returns: The NodeId.

static NodeId UnifiedAutomation.UaServer.ProgramStateMachineModel.GetNodeId ( Transition transition )

static

Retrieves the NodeId for the given transition value.

Parameters

transition The transition to get the NodeId.

Returns: The NodeId.

static IEnumerable<Transition> UnifiedAutomation.UaServer.ProgramStateMachineModel.GetTransitions	(	State	oldState,
		State	newState
	)

static

A sequence of all possible transition for the given states.

Parameters

oldState	The From state.
newState	The To state.

Returns: A sequence of all possible transition for the given states. The sequence can be empty, but it will never be null.

void UnifiedAutomation.UaServer.ProgramStateMachineModel.RaiseSwitchedEvent	(	State?	oldState,
		State?	state,
		Transition?	transition
	)

Raises the Switched event.

virtual void UnifiedAutomation.UaServer.ProgramStateMachineModel.SwitchToState	(	State?	state,
		Transition?	transition = `null`
	)

virtual

Switch to the given state.

Parameters

state	The state.
transition	The transition.

If the transition value is null the method will take the first transition that is possible. If there is no possible transition or if a transition was passed that is not possible for the old and new state combination, null will be assigned to the InternalTransition and FiniteStateMachineModel.LastTransition properties. It is up to the caller to avoid such situations.

A null value for the state will be translated to the specification conform status code StatusCodes.BadStateNotActive.
