Interface ExternalArcDefinition

All Known Implementing Classes:

XmlExternalArc

public interface ExternalArcDefinition

An ExternalArcDefinition is the result of the translation of a certain external source containing the definition of a process. That external source may contain necessary information to create an Arc pointing to a Node defined in another definition. That information is translated into an ExternalArcDefinition through a ProcessDefinitionTranslator. This ExternalArcDefinition will then in its turn be used by the GraphLoader to create an Arc through the GraphFactory. The default kind of external source is an XML file containing <arc> tags with external attribute. This external attribute must reference an existing external definition within the same file.
