Method Detail

variableKeys

public java.util.List<java.lang.Object> variableKeys()

Description copied from interface: State

Returns the list of state variable keys.

Specified by:

variableKeys in interface State

Returns:

the list of state variable keys.

get

public java.lang.Object get(java.lang.Object variableKey)

Description copied from interface: State

Returns the value for the given variable key. Changes to the returned value are not guaranteed to modify the state.

Specified by:

get in interface State

Parameters:

variableKey - the variable key

Returns:

the value for the given variable key

copy

public State copy()

Description copied from interface: State

Returns a copy of this state suitable for creating state transitions. This copy may be a shallow copy or deep copy and is domain specific. The State implementation may indicate its copy level with the DeepCopyState or ShallowCopyState annotations. If it is a shallow copy, you should not *directly* modify any fields of a copied state without copying the fields first, or it could contaminate the state from which the copy was made. Alternatively, use the MutableState.set(Object, Object) method to modify ShallowCopyState copied states, which for ShallowCopyState instances should perform a safe copy-on-write operation.

Specified by:

copy in interface State

Returns:

a copy of this state.

incrementWithChange

public HistoryState incrementWithChange(State newState,
                                        JointAction lastAction)

keyIndex

protected int keyIndex(java.lang.Object key)

arrayIndexForStepsBack

protected int arrayIndexForStepsBack(int ind)
