-/**
- * A basic tool for making connection on diagrams.
- *
- * This version defines the starting, ending and route points of a connection.
- * The routing itself is left up to the diagram router employed by
- * {@link DiagramUtils#validateAndFix(IDiagram, ICanvasContext)}.
- *
- * Manual:
- *
- * This tool is added to the diagram when a connection sequence is initiated by
- * another participant. PointerInteractor is one such participant which adds the
- * tool when a terminal or non-terminal-occupied canvas space is ALT+clicked
- * (see {@link PointerInteractor#checkInitiateConnectTool(MouseEvent, Point2D)}
- * ). The connection will be finished when another allowed terminal is clicked
- * upon or empty canvas space is ALT+clicked. Route points for the connection
- * can be created by clicking around on non-terminal-occupied canvas space while
- * connecting.
- *
- *
- * Connections can be started from and ended in flags by pressing ALT while
- * left-clicking.
