Diagram connectors must either have input transitions or a single outgoing transition. A statechart can have at most one target diagram connector of each label, but it can have several source diagram connectors with the same label.
During code generation, IBM® Rational® Rhapsody® flattens all junctions and diagram connectors by merging the common suffix to each segment entering the connector.
In both diagram and merge nodes, a label that belongs to an incoming segment is shared and duplicated during code generation among outgoing segments of that connector. The product merges the guards (conjunction), then concatenates the actions.
Diagram connectors connect different sections of the same statechart, whereas EnterExit points connect different statecharts. See EnterExit points.
