Class RtfByteArrayBuffer

java.lang.Object
java.io.OutputStream
com.lowagie.text.rtf.document.output.RtfByteArrayBuffer
All Implemented Interfaces:
Closeable, Flushable, AutoCloseable
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).
