  jpaul.Misc.UComp<T>

All Implemented Interfaces:

java.util.Comparator<T>

public class UComp<T>
extends java.lang.Object
implements java.util.Comparator<T>

UComp is an universal comparator, which compares any two objecs by simply comparing their string representation. It is useful when you need a deterministic string representation of a set (for debug purposes). As sets don't have any ordering info, two equal sets could have different representations; instead you can convert the set to an array of elements, sort it with the help of this universal comparator and print it.

Method Detail

compare

public int compare(T o1,
                   T o2)

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the string representation of the first argument is less than, equal to, or greater to the string representation of the second.

Specified by:

compare in interface java.util.Comparator<T>

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal" to" this Comparator. The easiest implementation: always return false unless obj == this.

Specified by:

equals in interface java.util.Comparator<T>

Overrides:

equals in class java.lang.Object
