A RecordingOutputStream can be wrapped around any other OutputStream to record all bytes written to it. You can then request a ReplayInputStream to read those bytes. <p>The RecordingOutputStream uses an in-memory buffer and backing disk file to allow it to record streams of arbitrary length limited only by available disk space. <p>As long as the stream recorded is smaller than the in-memory buffer, no disk access will occur. <p>Recorded content can be recovered as a ReplayInputStream (via getReplayInputStream() or, for only the content after the content-begin-mark is set, getContentReplayInputStream() ) or as a ReplayCharSequence (via getReplayCharSequence()). <p>This class is also used as a straight output stream by <A HREF="../../../org/archive/io/RecordingInputStream.html" title="class in org.archive.io"><CODE>RecordingInputStream</CODE></A> to which it records all reads. <A HREF="../../../org/archive/io/RecordingInputStream.html" title="class in org.archive.io"><CODE>RecordingInputStream</CODE></A> is exploiting the file backed buffer facility of this class passing <code>null</code> for the stream to wrap.
