6.8 Route services
6.8.1 Route representation
Route services are implemented as the interface X3DRoute. This interface has four methods as defined in the remainder of this subclause.
6.8.2 getSourceNode
X3DNode X3DRoute.getSourceNode()
    throws InvalidOperationTimingException,
           InvalidRouteException
The node representation that is used at the source of the ROUTE is returned.
6.8.3 getSourceField
String X3DRoute.getSourceField()
    throws InvalidOperationTimingException,
           InvalidRouteException
The name of the source field in the source node is returned.
6.8.4 getDestinationNode
X3DNode X3DRoute.getDestinationNode()
    throws InvalidOperationTimingException,
           InvalidRouteException
The node representation that is used at the source of the ROUTE is returned.
6.8.5 getDestinationField
String X3DRoute.getDestinationField()
    throws InvalidOperationTimingException,
           InvalidRouteException
The name of the destination field in the node is returned.
6.8.6 dispose
void X3Route.dispose()
    throws InvalidOperationTimingException
