Class UnitsNumberStringComparator

java.lang.Object

org.unix4j.util.sort.UnitsNumberStringComparator

All Implemented Interfaces:

Comparator<CharSequence>

public class UnitsNumberStringComparator
extends Object
implements Comparator<CharSequence>

A comparator for decimal strings sorted numerically, first by numeric sign; then by SI suffix (either empty, or 'k' or 'K', or one of 'MGTPEZY', in that order); and finally by numeric value. For example, '1023M' sorts before '1G' because 'M' (mega) precedes 'G' (giga) as an SI suffix.

The syntax for numbers is the same as for DecimalNumberStringComparator; the SI suffix must immediately follow the number.
