Parameters:   newState - The new state required. Parameters:   throwException - Causes an exception to be thrown if the transitionwould be illegal. final public  int checkTransition(int newState, boolean throwException)      Returns the action required to transition to a specified state. Parameters:   newState - The new state required. Parameters:   throwException - Causes an exception to be thrown if the transitionwould be illegal. final public  boolean equals(Object obj)      Tests for object identity. abstract protected  int[] getActionsByState()      Returns the transitions from the current state, indexed by new state. Illegal transitions are marked by the array element value WMObjectState.ILLEGAL_ACTION . Array of action codes. final public  WMObjectState[] getStates()      Returns the list of states to which legal transitions are possible. abstract protected  int[] getStatesByAction()      Returns the transitions from the current state, indexed by action.

Parameters:   action - Action code. final public  String stringValue()      Returns the object state as a string. final public  String toString()      final public  int value()      Returns the object state as an integer. protected static  WMObjectState valueOf(String[] tags, WMObjectState[] values, String state)      Field Detail DEFAULT_INT final public static int DEFAULT_INT(Code) Signifies that the object remains in its current state. FORCED_ACTION final public static int FORCED_ACTION(Code) Action is illegal to API caller, but is being forced by the engine. ILLEGAL_ACTION final public static int ILLEGAL_ACTION(Code) Action is invalid for the current state. MESSAGE final public static String MESSAGE(Code) NO_ACTION final public static int NO_ACTION(Code) Action does not cause a state transition. _state protected int _state(Code) The object state code. Constructor Detail WMObjectState protected WMObjectState(int state)(Code) Construct a new WMObjectState. The array type parameters are references to arrays statically defined in the calling subclass. Parameters:   state - The integer code for this state. Method Detail checkTransition final public int checkTransition(WMObjectState newState, boolean throwException) throws WMTransitionNotAllowedException(Code) Returns the action required to transition to a specified state. Parameters:   newState - The new state required. Parameters:   throwException - Causes an exception to be thrown if the transitionwould be illegal. Action code. throws:   WMTransitionNotAllowedException - if a transition from the currentstate to the new state would be illegal. checkTransition final public int checkTransition(int newState, boolean throwException) throws WMTransitionNotAllowedException(Code) Returns the action required to transition to a specified state. Parameters:   newState - The new state required. Parameters:   throwException - Causes an exception to be thrown if the transitionwould be illegal. Action code. throws:   WMTransitionNotAllowedException - if a transition from the currentstate to the new state would be illegal. equals final public boolean equals(Object obj)(Code) Tests for object identity. Only one instance of each ordinal value can ever exist. Parameters:   obj - The with which to compare object this instance. true if the two references point to the same object. getActionsByState abstract protected int[] getActionsByState()(Code) Returns the transitions from the current state, indexed by new state. Illegal transitions are marked by the array element value WMObjectState.ILLEGAL_ACTION . Array of action codes.
