Class ByteBuffer

com.sun.tools.javac.util.ByteBuffer

public class ByteBuffer
extends Object

A byte buffer is a flexible array which grows when elements are appended. There are also methods to append names to byte buffers and to convert byte buffers to names.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.
