Interface Connector

All Superinterfaces:

java.io.Serializable, Storable

All Known Implementing Classes:

AbstractConnector, ChopBoxConnector, ChopEllipseConnector, ChopPolygonConnector, LocatorConnector, PolyLineConnector, ShortestDistanceConnector

public interface Connector
extends java.io.Serializable, Storable

Connectors know how to locate a connection point on a figure. A Connector knows its owning figure and can determine either the start or the endpoint of a given connection figure. A connector has a display box that describes the area of a figure it is responsible for. A connector can be visible but it doesn't have to be.
Design Patterns

Strategy
Connector implements the strategy to determine the connections points.
Factory Method
Connectors are created by the Figure's factory method connectorAt.

Figure.connectorAt(int, int), ConnectionFigure

Method Summary

Modifier and Type	Method and Description
boolean	containsPoint(int x, int y) Tests if a point is contained in the connector.
java.awt.Rectangle	displayBox() Gets the display box of the connector.
void	draw(java.awt.Graphics g) Draws this connector.
java.awt.Point	findEnd(ConnectionFigure connection) Finds the end point for the connection.
java.awt.Point	findStart(ConnectionFigure connection) Finds the start point for the connection.
Figure	owner() Gets the connector's owner.

Method Detail

findStart

java.awt.Point findStart(ConnectionFigure connection)

Finds the start point for the connection.

findEnd

java.awt.Point findEnd(ConnectionFigure connection)

Finds the end point for the connection.

owner

Figure owner()

Gets the connector's owner.

displayBox

java.awt.Rectangle displayBox()

Gets the display box of the connector.

containsPoint

boolean containsPoint(int x,
                      int y)

Tests if a point is contained in the connector.

draw

void draw(java.awt.Graphics g)

Draws this connector. Connectors don't have to be visible and it is OK leave this method empty.
