The following UML class diagram summarizes all classes
related to
IlvLinkShapePolicy. Subclasses of
IlvPolicyAwareLinkImage can
have link shape policies. Normally, link shape policies can be shared
by different links. Subclasses of IlvAbstractLinkShapePolicy allow
you to link the policies using the child policy handle. This allows
you to install multiple policies on a link. The IlvCrossingLinkShapePolicy calculates
the crossing points of an IlvCrossingAwareLinkImage.
The crossings are drawn using a crossing graphic; that is, an IlvGraphic that
additionally implements the IlvCrossingGraphic interface.
