Class RtfByteArrayBuffer

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    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).
