Examples of org.jgroups.util.ExposedByteArrayOutputStream

org.jgroups.util.ExposedByteArrayOutputStream
Extends ByteArrayOutputStream, but exposes the internal buffer. This way we don't need to call toByteArray() which copies the internal buffer @author Bela Ban

        TpHeader hdr=(TpHeader)msg.getHeader(this.id);
        if(hdr == null)
            throw new Exception("message " + msg + " doesn't have a transport header, cannot route it");
        String group=hdr.channel_name;


        ExposedByteArrayOutputStream out_stream=new ExposedByteArrayOutputStream((int)(msg.size() + 50));
        ExposedDataOutputStream dos=new ExposedDataOutputStream(out_stream);


        writeMessage(msg, dos, multicast);
        Buffer buf=new Buffer(out_stream.getRawBuffer(), 0, out_stream.size());


        if(stats) {
