oracle.javatools.db.diff
Class GenericComparator

java.lang.Object
  extended by oracle.javatools.db.diff.GenericComparator

All Implemented Interfaces:
java.util.Comparator

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

Generic comparator for use comparing lists of objects. Compares using the following rules (in order):

  1. If both objects are Comparable, they are compared using the Comparable interface
  2. If the object is convertible to a string using the javatools ToStringManager the string representation is compared.
  3. toString is used to create a String representation that is then compared.

For non primitive objects, this Comparator is only designed to compare lists that contains objects all of the same class.

When dealing with numbers, a String representation of a number, and its Number representation will equate, as will different Number implementations. i.e. "1", 1 and 1D are all the same to this Comparator, but all number representations will compare in numerical, not alphabetical order so "10" is greater than "2".

Since:
11
