Class VectorComparator

java.lang.Object
  peersim.vector.VectorComparator

All Implemented Interfaces:

java.util.Comparator

public class VectorComparator
extends java.lang.Object
implements java.util.Comparator

This class provides a generic implementation of the java.lang.Comparator interface specialized for Node objects. Nodes are compared based on one of their protocols, on which a configurable method is invoked. Both the protocol id and the method are specified in the constructor.
This comparator can be used, for example, to sort an array of nodes based on method getValue associated to the protocol pid:

 Comparator c = new VectorComparator(pid, "getValue");
 Array.sort(Node[] array, c);
 

Note that differently from other classes in this package, VectorComparator is declared programmatically in the code and not in the configuration file. It is included in this package because it shares the same philosophy of the other classes.
