| TransitionImpl | | public class TransitionImpl implements ITransition(Code) | | Nearly-Immutable implementation of ITransition. As an immutable, transitions
cannot be created if there are cycles in the state machine. Therefore,
there needs to be a way to post-creation correctly populate the Transition's
destination state. Thus, the destination state may be set once.

| Method Summary | |
| public IAction | getAction()
Returns the action used to transition to the destination state. | | public IState | getDestinationState()
Returns the next state if the corresponding action is executed. | | public String | getName()
Retrieves the name for the transition. | | public IValidate[] | getValidates()
Returns all validation methods used to assert that the system can
perform this transition. | | public boolean | isDestinationStateSet()
Allows for a builder system to detect if the destination state has
been set or not, without causing the IllegalStateException through
the getDestinationState(). | | public void | setDestinationState(IState dest)
Allows for post-creation setting of the destination. | | public String | toString()
|
| getAction | | public IAction getAction()(Code) | | Returns the action used to transition to the destination state.
transition's action, which can never be null. |
| getDestinationState | | public IState getDestinationState()(Code) | | Returns the next state if the corresponding action is executed.
destination state, which can never be null. |
| getName | | public String getName()(Code) | | Retrieves the name for the transition. This should be unique for
state-machine assembly purposes, but it does not have to be.
a non-null name for this transition. |
| getValidates | | public IValidate[] getValidates()(Code) | | Returns all validation methods used to assert that the system can
perform this transition.
a list of associated validation instances. |
| isDestinationStateSet | | public boolean isDestinationStateSet()(Code) | | Allows for a builder system to detect if the destination state has
been set or not, without causing the IllegalStateException through
the getDestinationState().
|
| setDestinationState | | public void setDestinationState(IState dest)(Code) | | Allows for post-creation setting of the destination. The destination
may only be set to a non-null value once. If there is an
attempt to pull the destination through getDestinationState()
and it has not been set yet, then an IllegalStateException will
be thrown.
