Class AutoString

ifs.fnd.buffer.AutoString

All Implemented Interfaces:

java.lang.Cloneable

public final class AutoString
extends java.lang.Object
implements java.lang.Cloneable

This class can be used instead of java.lang.StringBuffer. It has better performance but is not safe for use by multiple threads. Consider using StringBuilder instead.
