• Interface Summary 

  Interface	Description
  Context	A Context or "scope" for storing variables; usually tied to a SCXML root or State object.
  ErrorReporter	An interface for reporting SCXML errors to the host environment, containing the definition of commonly occuring errors while executing SCXML documents.
  Evaluator	Interface for a component that may be used by the SCXML engines to evaluate the expressions within the SCXML document.
  EvaluatorProvider	An EvaluatorProvider provides an Evaluator instance for a specific SCXML datamodel type.
  EventDispatcher	The event controller interface used to send messages containing events or other information directly to another SCXML Interpreter, other external systems using an Event I/O Processor or to raise events in the current SCXML session.
  PathResolver	Interface for a component that may be used by the SCXML engines to resolve context sensitive paths.
  SCXMLIOProcessor	The SCXML I/O Processor provides the interface for either an internal process or an external system or invoked child SCXML process (Invoker) to send events into the SCXML processor queue.
  SCXMLListener	Listener interface for observable entities in the SCXML model.
  SCXMLSemantics	The purpose of this interface is to separate the the W3C SCXML Algorithm for SCXML Interpretation from the SCXMLExecutor and therefore make it pluggable.

• Class Summary 

  Class	Description
  ActionExecutionContext	ActionExecutionContext providing restricted access to the SCXML model, instance and services needed for the execution of Action instances
  Builtin	Implementation of the SCXML specification required In() builtin predicate.
  EvaluatorFactory	A static singleton factory for EvaluatorProviders by supported SCXML datamodel type.
  NotificationRegistry	The registry where SCXML listeners are recorded for nodes of interest such as the SCXML root, EnterableStates and Transitions.
  SCInstance	The SCInstance performs book-keeping functions for a particular execution of a state chart represented by a SCXML object.
  SCXMLExecutionContext	SCXMLExecutionContext provides all the services and internal data used during the interpretation of an SCXML statemachine across micro and macro steps
  SCXMLExecutor	The SCXML "engine" that executes SCXML documents.
  SCXMLSystemContext	The SCXMLSystemContext is used as a read only Context wrapper and provides the SCXML (read only) system variables which are injected via the unwrapped SCXMLSystemContext.getContext().
  StateConfiguration	The current active states of a state machine
  Status	The immutable encapsulation of the current state of a state machine.
  TriggerEvent	A class representing an event.
  XPathBuiltin	Implementation and support of Commons SCXML builtin predicates to support XPath based datamodel operations for non-XPath languages.

• Enum Summary 

  Enum	Description
  Evaluator.AssignType	The allowable types of including and in particular when using XPath

• Exception Summary 

  Exception	Description
  SCXMLExpressionException	Exception thrown when a malformed expression is encountered during evaluation of an expression in a SCXML document.
