Enum Summary

Enum	Description
FSMBuilderException.ErrorCode	There are many different issues that can occur when building the state machine and instead of having individual exceptions for everything, we have these error codes.

Exception Summary

Exception	Description
ActionAlreadyDefinedException	Indicates that an action was already associated with the object (State or Transition)
DefaultTransitionAlreadySpecifiedException	You can only have a single default transition for a transient state.
FinalStateAlreadyDefinedException	Indicates that you tried to define a final state twice.
FinalStateIsTransientException	Indicates that you tried to define the final state as transient, which you cannot do.
FinalStateTransitionsException	Indicates that you tried to define transitions on a final state.
FSMBuilderException
GuardAlreadyDefinedException	Indicates that a guard was already associated with the object (State or Transition)
IllegalTransformationOnTransitionException	You can optionally specify a transformation with your transition but you can only do so if the state you are transitioning to is a so-called transient state.
InitialStateAlreadyDefinedException	Indicates that you tried to define an initial state twice.
StateAlreadyDefinedException	You can only define the same state once.
StateBuilderException
StateNotDefinedException	If you define a transition from A to B but then you never end up defining the state B, you will get this exception thrown when trying to build the FSM.
TransientLoopDetectedException	If you would be able to specify a transition from a transient state to another transient state (or itself) you will likely end up in a loop.
TransientStateMissingTransitionException	Indicates that you defined a transient state but didn't specify any default transitions, which you must for a transient state or you will get stuck in that state and then it wouldn't be a transient state, now would it!
TransitionMissingException	Indicates that you didn't define any transitions for the given state.
