Writes the complete contents of this ByteArrayOutputStream to the specified output stream argument, as if by calling the output stream's write method using out.write(buf, 0, count) .

Usage

From source file:org.springframework.flex.http.AmfHttpMessageConverter.java

private void writeObject(Object data, HttpOutputMessage outputMessage, AmfTrace trace) throws IOException {
    ByteArrayOutputStream outBuffer = new ByteArrayOutputStream();
    Amf3Output serializer = new Amf3Output(new SerializationContext());
    serializer.setOutputStream(outBuffer);
    serializer.setDebugTrace(trace);/*from w  w  w .ja  v  a 2 s  .  com*/
    try {
        serializer.writeObject(data);
        outBuffer.flush();
        outBuffer.close();
        outputMessage.getHeaders().setContentLength(outBuffer.size());
        outBuffer.writeTo(outputMessage.getBody());
    } catch (SerializationException se) {
        throw new HttpMessageNotWritableException("Could not write " + data + " as AMF message.", se);
