java.lang.Objectorg.apache.tomcat.util.buf.CharChunk
public final class CharChunk
Utilities to manipluate char chunks. While String is the easiest way to manipulate chars ( search, substrings, etc), it is known to not be the most efficient solution - Strings are designed as imutable and secure objects.
