public class ConnectionTool
extends AbstractTool
A tool that can be used to connect figures, to split connections, and to join two segments of a connection. ConnectionTools turns the visibility of the Connectors on when it enters a figure. The connection object to be created is specified by a prototype.
Design Patterns

o Prototype
ConnectionTools creates the connection by cloning a prototype.

See Also:
ConnectionFigure, clone

o createConnection()
Creates the ConnectionFigure.
o createdFigure()
Gets the currently created figure
o deactivate()
Deactivates the tool.

Adjust the created connection or split segment.
o mouseMove(MouseEvent, int, int)
Handles mouse move events in the drawing view.

Constructors

o ConnectionTool 
 public ConnectionTool(DrawingView view,
                       ConnectionFigure prototype)

Methods

o mouseMove 
 public void mouseMove(MouseEvent e,
                       int x,
                       int y)
Handles mouse move events in the drawing view.

Overrides:
mouseMove in class AbstractTool
o mouseDown 
 public void mouseDown(MouseEvent e,
                       int x,
                       int y)
Manipulates connections in a context dependent way. If the mouse down hits a figure start a new connection. If the mousedown hits a connection split a segment or join two segments.

Overrides:
mouseDown in class AbstractTool
o mouseDrag 
 public void mouseDrag(MouseEvent e,
                       int x,
                       int y)
Adjust the created connection or split segment.

Overrides:
mouseDrag in class AbstractTool
o mouseUp 
 public void mouseUp(MouseEvent e,
                     int x,
                     int y)
Connects the figures if the mouse is released over another figure.

Overrides:
mouseUp in class AbstractTool
o deactivate 
 public void deactivate()
Deactivates the tool.

Overrides:
deactivate in class AbstractTool
o createConnection 
 protected ConnectionFigure createConnection()
Creates the ConnectionFigure. By default the figure prototype is cloned.

o findSource 
 protected Figure findSource(int x,
                             int y,
                             Drawing drawing)
Finds a connectable figure target.

o findTarget 
 protected Figure findTarget(int x,
                             int y,
                             Drawing drawing)
Finds a connectable figure target.

o findConnection 
 protected ConnectionFigure findConnection(int x,
                                           int y,
                                           Drawing drawing)
Finds an existing connection figure.

o createdFigure 
 protected ConnectionFigure createdFigure()
Gets the currently created figure

o trackConnectors 
 protected void trackConnectors(MouseEvent e,
                                int x,
                                int y)
o findConnectionStart 
 protected Figure findConnectionStart(int x,
                                      int y,
                                      Drawing drawing)
Finds a connection start figure.

o getStartConnector 
 protected Connector getStartConnector()
o getEndConnector 
 protected Connector getEndConnector()
o getTarget 
 protected Connector getTarget()
