      extended by com.lowagie.text.rtf.document.output.RtfByteArrayBuffer
All Implemented Interfaces:
java.io.Closeable, java.io.Flushable

public final class RtfByteArrayBuffer
extends java.io.OutputStream

A RtfByteArrayBuffer works much like ByteArrayOutputStream but is cheaper and faster in most cases (exception: large writes when reusing buffers).
