Constructs a connector with the given owner figure.

Method Detail

owner

public Figure owner()

Gets the connector's owner.

Specified by:

owner in interface Connector

findStart

public java.awt.Point findStart(ConnectionFigure connection)

Description copied from interface: Connector

Finds the start point for the connection.

Specified by:

findStart in interface Connector

findEnd

public java.awt.Point findEnd(ConnectionFigure connection)

Description copied from interface: Connector

Finds the end point for the connection.

Specified by:

findEnd in interface Connector

findPoint

protected java.awt.Point findPoint(ConnectionFigure connection)

Gets the connection point. Override when the connector does not need to distinguish between the start and end point of a connection.

displayBox

Gets the display box of the connector.

Specified by:

displayBox in interface Connector

containsPoint
