Interface Summary

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.
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.
SCXMLListener	Listener interface for observable entities in the SCXML model.
SCXMLSemantics	The purpose of this interface is to separate the interpretation algorithm from the SCXMLExecutor and therefore make it pluggable.

Class Summary

Builtin	Implementations of builtin functions defined by the SCXML specification.
NotificationRegistry	The registry where SCXML listeners are recorded for nodes of interest such as the SCXML root, TransitionTargets and Transitions.
SCInstance	The SCInstance performs book-keeping functions for a particular execution of a state chart represented by a SCXML object.
SCXMLExecutor	The SCXML "engine" that executes SCXML documents.
SCXMLHelper	Helper class, all methods static final.
Status	The encapsulation of the current state of a state machine.
