build

public Definition<S,C,D> build()
                        throws FSMBuilderException

Build the definition of the state machine and validate that all is well. The following rules will be validate upon building the definition:

• Transitions with transformations can only be going to transient states and anything else is not allowed, hence, we will throw an exception.

Returns:

Throws:

FSMBuilderException - in case any issues with the FSM is detected.
