Class NumbersAwareStringComparator

java.lang.Object

org.conqat.lib.commons.string.NumbersAwareStringComparator

All Implemented Interfaces:

java.util.Comparator<java.lang.String>

public class NumbersAwareStringComparator
extends java.lang.Object
implements java.util.Comparator<java.lang.String>

Compares two strings lexicographically, except at locations in the strings where numbers should be compared. In this case, the value of the number is compared. Useful for cases such as comparing "foo 5" to "foo 20", where the digit 2 is lexicographically before the digit 5, leading to an undesired sorting result.
