Class ComparatorTypes

java.lang.Object
  com.jstatcom.util.ComparatorTypes

All Implemented Interfaces:

java.util.Comparator<java.lang.Object>

public abstract class ComparatorTypes
extends java.lang.Object
implements java.util.Comparator<java.lang.Object>

This class contains comparators that can be reused by other classes.

It implements the typesave enum pattern (Joshua Bloch, "Effective Java", Item 21) . If you compare ComparatorTypes, always use the == operator. This is save, because they are Singletons (Gamma et al., 1995) .
