Description copied from interface: TransitionBuilder

For transitions to a transient state, you can optionally specify a transformation that will be applied to the original event before entering the state you're automatically transitioning to. NOTE: the validation that the target state is indeed a transient state cannot be performed until the actual state machine definition is built (FSMBuilder.build()) so if you specify a transformation on a Transition that go to a "regular" state, then it will not be detected until later at which time an FSMBuilderException will be thrown.

Specified by:

withTransformation in interface TransitionBuilder<E,S extends Enum<S>,C extends Context,D extends Data>

Returns:

Throws:

IllegalStateException - in case a transformation has already been specified.

build

public Transition<E,S,C,D> build()
