  performative name --> Arc

Constructor Detail

### State

    public State(java.lang.String stateId)

  Constructs a new State object.
  Parameters:
    `stateId` - unique state identifier within the fsm

### State

    public State(java.lang.String stateId,
                 FsmClass fsmClass)

  Constructs a new State object.
  Parameters:
    `stateId` - unique state identifier within the fsm
    `fsmClass` - the fsm class containing this new state

### State

    public State(java.lang.String stateId,
                 Fsm fsm)

  Constructs a new State object.
  Parameters:
    `stateId` - unique state identifier within the fsm
    `fsm` - the fsm containing this new state

Method Detail

### getStateId

    public java.lang.String getStateId()

  Returns the state id.
  Returns:
    the state id

### getArcs

    public java.util.Collection getArcs()

  Returns the collection of the arcs from this state.
  Returns:
    the collection of the arcs from this state

### addArc

    public void addArc(Arc arc)

  Records the arc to take when the its performative is observed.
  Parameters:
    `arc` - the FSM arc which specifies a transition-to state and an action

### addArc

    public void addArc(Performative performative,
                       Arc arc)

  Records the arc to take when the given performative is observed.
  Parameters:
    `performative` - the given performative
    `arc` - the FSM arc which specifies a transition-to state and an action

### getArc

    public Arc getArc(Performative performative)

  Returns the arc to take for the given performative.
  Parameters:
    `performative` - the given performative
  Returns:
    the FSM arc which specifies a transition-to state and an action

### compareTo

    public int compareTo(java.lang.Object object)

  Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
  Specified by:
    `compareTo` in interface `java.lang.Comparable`
  Parameters:
    `object` - the reference object with which to compare.
  Returns:
    a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object

### equals

    public boolean equals(java.lang.Object object)

  Returns `true` iff some object equals this object
  Overrides:
    `equals` in class `java.lang.Object`
  Parameters:
    `object` - the `Object` for equality comparison
  Returns:
    equals `boolean` value indicating equality or non-equality.

### toString

    public java.lang.String toString()

  Returns the string representation of the `State`
  Overrides:
    `toString` in class `java.lang.Object`
  Returns:
    the representation of the `State` as a `String`

### clone

    public java.lang.Object clone()

  Creates a clone of this object.
  Overrides:
    `clone` in class `java.lang.Object`
