Examples of research.ConnectionFigure

research.ConnectionFigure
Figures to connect Connectors provided by Figures. A ConnectionFigure knows its start and end Connector. It uses the Connectors to locate its connection points.
A ConnectionFigure can have multiple segments. It provides operations to split and join segments.
Design Patterns
Strategy
Strategy is used encapsulate the algorithm to locate the connection point. ConnectionFigure is the Strategy context and Connector is the Strategy.
Observer
Observer is used to track changes of the connected figures. A connection figure registers itself as listeners or observers of the source and target connector.
