Package edu.uci.ics.jung.graph.util
Class Graphs
java.lang.Object
edu.uci.ics.jung.graph.util.Graphs
Provides specialized implementations of
GraphDecorator
. Currently these
wrapper types include "synchronized" and "unmodifiable".
The methods of this class may each throw a NullPointerException
if the graphs or class objects provided to them are null.
