Interface Summary

Interface	Description
Event<S extends Enum<S>>	An Event captures the information that may trigger a Transition in a FiniteStateMachine from one state to another.
ExecutionContext	Provides contextual information about a FiniteStateMachine, typically to aid in runtime decision making for actions (eg: TransitionActions, StateEntryActions and/or StateExitActions) and Events.
FiniteStateMachine<S extends Enum<S>>	A FiniteStateMachine implements a general purpose finite-state-machine.
FiniteStateMachineListener<S extends Enum<S>>	A FiniteStateMachineListener listens for state related events on a FiniteStateMachine.
Instruction	A marker interface for Instructions to FiniteStateMachines.
LifecycleAwareEvent<S extends Enum<S>>	A LifecycleAwareEvent is a specialized Event that receives callbacks during the processing of the Event by a FiniteStateMachine.
Model<S extends Enum<S>>	A Model represents the definition of a FiniteStateMachine, the set of known states, Transitions between said states and StateEntryActions / StateExitActions to be performed when said states are changed.
NonBlockingFiniteStateMachine.TaskDependencies	Dependencies for Task.
StateEntryAction<S extends Enum<S>>	A StateEntryAction encapsulates the actions to be performed by a FiniteStateMachine when a particular state is entered.
StateExitAction<S extends Enum<S>>	A StateExitAction encapsulates the actions to be performed by a FiniteStateMachine when leaving a known state.
TransitionAction<S extends Enum<S>>	A TransitionAction encapsulates the actions to be performed as part of the Transition from one state to another.

Class Summary

Class	Description
AnnotationDrivenModel<S extends Enum<S>>	An AnnotationDrivenModel is a Model created through extracting information defined by Transitions annotation.
Instruction.ProcessEvent<S extends Enum<S>>	An Instruction for a FiniteStateMachine to process an Event.
Instruction.TransitionTo<S extends Enum<S>>	An Instruction for a FiniteStateMachine to Instruction.TransitionTo another state.
NonBlockingFiniteStateMachine<S extends Enum<S>>	An NonBlockingFiniteStateMachine is a specialized FiniteStateMachine implementation that performs transitions asynchronously to the threads that request state changes.
NonBlockingFiniteStateMachine.CoalescedEvent<S extends Enum<S>>	A NonBlockingFiniteStateMachine.CoalescedEvent is a LifecycleAwareEvent that coalesces other (wrapped) Events with the same discriminator so that only one Event actually executes.
NonBlockingFiniteStateMachine.CoalescedEvent.Discriminator	A NonBlockingFiniteStateMachine.CoalescedEvent.Discriminator is an object that is used to uniquely differentiate events to be coalesced, scoped by a NonBlockingFiniteStateMachine.
NonBlockingFiniteStateMachine.DefaultTaskDependencies	Implementation of Dependencies for Task
NonBlockingFiniteStateMachine.DelayedTransitionTo<S extends Enum<S>>	A NonBlockingFiniteStateMachine.DelayedTransitionTo is a specialized Instruction for NonBlockingFiniteStateMachines that enables a StateEntryAction to request a delayed transition to another state, unlike a Instruction.TransitionTo Instruction which occurs immediately.
NonBlockingFiniteStateMachine.ProcessEventLater<S extends Enum<S>>	A specialized Instruction for NonBlockingFiniteStateMachines that enables a StateEntryAction to request an Event to be processed at some point in the future.
NonBlockingFiniteStateMachine.SubsequentEvent<S extends Enum<S>>	A NonBlockingFiniteStateMachine.SubsequentEvent is an Event that ensures that another (wrapped) Event to occur if an only if the FiniteStateMachine is at a certain transition count.
ReflectionHelper	A collection of utilities to assist in using Reflection to create objects.
Render	Provides Render capabilities for FiniteStateMachines, in particular their Models.
SimpleModel<S extends Enum<S>>	A SimpleModel is a basic implementation of a Model for a FiniteStateMachine.
Transition<S extends Enum<S>>	A Transition represents a transition in a FiniteStateMachine from one or more possible states to a desired state.

Enum Summary

Enum	Description
NonBlockingFiniteStateMachine.CoalescedEvent.Process	The NonBlockingFiniteStateMachine.CoalescedEvent to process.

Exception Summary

Exception	Description
RollbackTransitionException	A RollbackTransitionException may be thrown during an TransitionAction for a Transition if the said Transition should be aborted.
