Usage

From source file:org.mule.transport.tcp.protocols.LengthProtocol.java

@Override
protected void writeByteArray(OutputStream os, byte[] data) throws IOException {
    // Write the length and then the data.
    DataOutputStream dos = new DataOutputStream(os);
    dos.writeInt(data.length);/* w  w w. j a  v  a  2 s . c o m*/
    dos.write(data);
    // DataOutputStream size is SIZE_INT + the byte length, due to the writeInt call
    // this should fix EE-1494
    if (dos.size() != data.length + SIZE_INT) {
        // only flush if the sizes don't match up
        dos.flush();
    }
