Package diva.canvas.connector

Support for "connectors," which are figures that draw themselves between sites on other figures. This package contains:

• The top-level interfaces for connectors
• Basic implementations of connectors
• Interfaces and concrete implementations of routers, which provides connectors with useful ways to draw themselves.

Interface Summary

Interface	Description
Connector	A Connector is a figure that draws itself between two sites on other figures.
ConnectorEnd	An interface for objects that can be attached to the end of a connector.
ConnectorListener	A listener for changes in a connector's connectivity.
ConnectorTarget	An object that is used to get suitable "target" sites for connectors.
ManhattanRouter	A ManhattanRouter is an object that routes Polylines as a series of perpendicular edges.
Router	A Router is an object that can be used to help a connector route itself.
Terminal	A Terminal is a figure that provides a visible place for connectors to connect to.

Class Summary

Class	Description
AbstractConnector	An abstract implementation of Connector.
AbstractConnectorTarget	An abstract implementation of the ConnectorTarget interface.
ArcConnector	A Connector that draws itself in an arc.
ArcInteractor	An interactor for dragging either end of an arc connector and for for altering the shape of the arc by dragging a midpoint grab handle.
ArcManipulator	A manipulator for arc connectors.
ArcMidpointSite	A concrete implementation of Site that is located in the center of the bounding box of a figure.
Arrowhead	An arrowhead that is drawn on the end of a connector.
AutonomousSite	A site that is not attached to a figure.
BasicManhattanRouter	A basic manhattan router.
Blob	An object that draws a blob of some kind on the end of a connector.
BoundsSite	A site that locates itself on the bounds of a figure's shape.
CenterSite	A concrete implementation of Site that is located in the center of the bounding box of a figure.
CenterTarget	An implementation of connector targets that finds center sites.
ConnectorAdapter	An adapter for connector listeners.
ConnectorEvent	A graph event that is emitted when anything interesting happens inside a graph by way of a GraphModel.
ConnectorInteractor	An interactor for dragging one end of a connector.
ConnectorManipulator	A manipulator which attaches grab handles to the ends of a connector.
FixedNormalSite	A site decorator that disallows changing the normal.
IncrManhattanRouter	A manhattan router which does only incremental routing and delegates static routing to another manhattan router implementation.
ManhattanConnector	A Connector that draws itself with perpendicular lines.
NullSite	A site that doesn't do anything useful.
ParametricSite	A site that locates itself in a figure at a location in X and Y that is some percentage of the bounding box of the figure.
PerimeterSite	A site that locates itself on the perimeter of a figure.
PerimeterTarget	A connector target that returns sites on the perimeter of a figure.
StraightConnector	A Connector that draws itself in a straight line.
StraightTerminal	A terminal that consists of a straight line plus an additional decoration at the connection end of the terminal.
TerminalFigure	A TerminalFigure decorates a figure to be a terminal as well.
