public class IlvGeneralLinkTunnelCrossings extends IlvAbstractCrossingGraphic
IlvGeneralLinkTunnelCrossings
instance is an auxiliary graphic
that is used in combination with an IlvGeneralLink
.
The tunnel crossing graphic draws the tunnel shapes for link crossings.
It must be in a manager layer that is above all layers that contain links.
Normally, the crossing link shape policy takes care of this automatically.
Notice that each link needs its own crossing graphic. Crossing graphics cannot be
shared by several links. A new tunnel crossing graphic together with a crossing
link shape policy are automatically installed at a general link when the
tunnel crossing mode is set,
by link.setCrossingMode(IlvGeneralLink.TUNNEL_CROSSINGS)
.
Usually, it is not necessary to install the tunnel graphic explicitly,
because the crossing mode of IlvGeneralLink
handles it automatically.
The following example illustrates how to install a tunnel crossing
graphic that is updated by the crossing link shape policy explicitly:
IlvCrossingLinkShapePolicy policy = new IlvCrossingLinkShapePolicy(); // the policy can be shared by links, but each link needs its own // tunnel crossing object IlvGeneralLink link = new IlvGeneralLink(node1, node2, true, null); link.setCrossingGraphic(new IlvGeneralLinkTunnelCrossings(link)); link.setLinkShapePolicy(policy); ...
