The grapher provides a way to specify the contact points
you need on a graphic object. This is done by using
link connectors, which are subclasses
of the class
IlvLinkConnector,
The class
IlvLinkConnectoris dedicated to the computation of the connection
points of links. Subclasses of this abstract class can be used to
obtain contact points other than the default ones. An
IlvLinkConnector is
associated with a node. The implementation of the method
getConnectionPoint decides where the connection point of a link (provided
as an argument) should be located.
An instance of
IlvLinkConnector can
be specified for each node of a grapher. To do this, simply create
it using the constructor
IlvLinkConnector or use the method
attach. Notice that the same instance of link connector
cannot be shared by several nodes.
A link connector specified for a node controls the connection
points of all the links incident to this node. If you need the connection
points of the incident links not to all be computed in the same way
(that is, by the same link connector), you can specify a link connector
individually for each extremity of each link. To do this, simply create
it using the constructor
IlvLinkConnector(ilog.views.IlvLinkImage, boolean)
or use the method
attach(IlvLinkImage, boolean, boolean) .
Notice that the same link connector can be shared by
several links incident to the same node.
To get the instance of link connector actually used to
compute the contact point of a given link, use the static method
Get.
