Class SystemConstraint

java.lang.Object
oracle.spatial.network.SystemConstraint

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, NetworkConstraint

public class SystemConstraint

extends java.lang.Object

implements NetworkConstraint

This class defines the common network constraints for network analysis. It contains the must-avoid nodes and must-avoid links, the maximum cost, the maximun duration, the maximum distance, the maximum search depth (no of links in the path!), and a bounding MBR. This class implements NetworkConstraint interface.
