Class IntegerComparator

java.lang.Object
  org.openadaptor.util.comparator.IntegerComparator

All Implemented Interfaces:

java.util.Comparator

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

For JDK 1.1 compatibility, we need to provide our own Integer comparator to avoid a ClassCastException when using collections for JDK 1.1.

This is because java.lang.String implements java.util.Comparable but Collections for JDK 1.1 is expecting an object which implements com.sun.java.util.collections.Comparable.
