io.microsphere.util.CharSequenceComparator

All Implemented Interfaces:

java.util.Comparator<java.lang.CharSequence>

public class CharSequenceComparator
extends java.lang.Object
implements java.util.Comparator<java.lang.CharSequence>

A Comparator implementation for comparing CharSequence objects.

This class provides a consistent and null-safe comparison mechanism for CharSequence instances, primarily designed to be used in sorting and ordering operations.

Example Usage

 List<CharSequence> sequences = Arrays.asList("apple", "banana", "apple", null);
 Collections.sort(sequences, CharSequenceComparator.INSTANCE);
 

The comparison is based on lexicographical ordering similar to String.compareTo(String). Null values are considered smaller than non-null values. When both sequences are null, they are considered equal.
