Method Detail

getName

public String getName()

Description copied from interface: State

Name of the State. This value is persisted as the State value in the Stateful Entity.

Specified by:

getName in interface State<T>

Returns:

Name of the State

setName

public void setName(String name)

getTransition

public Transition<T> getTransition(String event)

Description copied from interface: State

Returns the Transition for an Event

Specified by:

getTransition in interface State<T>

Parameters:

event - The event

Returns:

The Transition for this event

getTransitions

public Map<String,Transition<T>> getTransitions()

setTransitions

public void setTransitions(Map<String,Transition<T>> transitions)

isEndState

public boolean isEndState()

Description copied from interface: State

Whether this State is an End State

Specified by:

isEndState in interface State<T>

Returns:

if true, then this is an End State

setEndState

public void setEndState(boolean isEndState)

addTransition

public void addTransition(String event,
                          State<T> next)

Description copied from interface: State

Add a deterministic Transition with no Action

Specified by:

addTransition in interface State<T>

Parameters:

event - The event to add the Transition

next - The next State

addTransition

public void addTransition(String event,
                          State<T> next,
                          Action<T> action)

Description copied from interface: State

Add a deterministic Transition with an Action

Specified by:

addTransition in interface State<T>

Parameters:

event - The event to add the Transition

next - The next State

action - The resulting Action

addTransition

public void addTransition(String event,
                          Transition<T> transition)

Description copied from interface: State

Add a Transition

Specified by:

addTransition in interface State<T>

Parameters:

event - The event to add the Transition

transition - The Transition

removeTransition

public void removeTransition(String event)

Description copied from interface: State

Remove a Transition from the State

Specified by:

removeTransition in interface State<T>

Parameters:

event - Remove the transition for this Event

setBlocking

public void setBlocking(boolean isBlocking)

Description copied from interface: State

Set whether or not this is a Blocking State

Specified by:

setBlocking in interface State<T>

Parameters:

isBlocking - if true, then this is a blocking State

isBlocking

public boolean isBlocking()

Description copied from interface: State

Whether this is a Blocking State. If Blocking, event will not process unless there is an explicit Transition for the event. If blocked, the FSM will retry the event until the FSM transitions out of the blocked State

Specified by:

isBlocking in interface State<T>

Returns:

if true, then State is a "blocking" state

toString

public String toString()

Overrides:

toString in class Object
