Class RtfByteArrayBuffer

java.lang.Object
  java.io.OutputStream
      com.lowagie.text.rtf.document.output.RtfByteArrayBuffer

All Implemented Interfaces:

Closeable, Flushable

public final class RtfByteArrayBuffer
extends OutputStream

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