| org.apache.commons.scxml.SCXMLSemantics
All known Subclasses: org.apache.commons.scxml.semantics.SCXMLSemanticsImpl,
| SCXMLSemantics | | public interface SCXMLSemantics (Code) | | The purpose of this interface is to separate the interpretation algorithm
from the SCXMLExecutor and therefore make it pluggable.
Semantics agnostic utility functions and common operators as defined in
UML can be found in the SCXMLHelper or attached directly to
the SCXML model elements. Some of the possible semantic interpretations
are, for example:
- STATEMATE
- RHAPSODY
- ROOMCharts
- UML 1.5
- UML 2.0
Specific semantics can be created by subclassing
org.apache.commons.scxml.semantics.SCXMLSemanticsImpl.
