Class ReverseEntryValueComparator

java.lang.Object
  moj.util.ReverseEntryValueComparator

All Implemented Interfaces:

java.util.Comparator<java.util.Map.Entry<java.lang.String,java.lang.Float>>

public class ReverseEntryValueComparator
extends java.lang.Object
implements java.util.Comparator<java.util.Map.Entry<java.lang.String,java.lang.Float>>

Comparator that compares values. Note that it compares the keys as well as the values. This is necessary to be consistent with Map.Entry.equals() and to ensure that our entrySet behaves like a Set.
