All Known Implementing Classes:

public interface NetworkConstraint
extends java.lang.Cloneable, java.io.Serializable

This interface defines a general network constraint for network analysis. A network constraint at the node level means that only the current node and the currrent link are considered. A network constraint at the path level means that some or all path information is considered during the search. Note the constraint is checked during the search and implemented by the users.

Method Summary

Modifier and Type	Method and Description
boolean	isSatisfied(AnalysisInfo info) Checks if the constraint is satisfied.
boolean	requiresPathLinks() Returns true if the constraint requires some or all path information.
