Example 1 with BufferEditor

use of org.fusesource.hawtbuf.BufferEditor in project fabric8 by jboss-fuse.

the class ClientInvokerImpl method request.

protected Object request(ProxyInvocationHandler handler, final String address, final UTF8Buffer service, final ClassLoader classLoader, final Method method, final Object[] args) throws Exception {
    if (!running.get()) {
        throw new IllegalStateException("DOSGi Client stopped");
    }
    final long correlation = correlationGenerator.incrementAndGet();
    // Encode the request before we try to pass it onto
    // IO layers so that #1 we can report encoding error back to the caller
    // and #2 reduce CPU load done in the execution queue since it's
    // serially executed.
    DataByteArrayOutputStream baos = new DataByteArrayOutputStream((int) (handler.lastRequestSize * 1.10));
    // we don't know the size yet...
    baos.writeInt(0);
    baos.writeVarLong(correlation);
    writeBuffer(baos, service);
    MethodData methodData = getMethodData(method);
    writeBuffer(baos, methodData.signature);
    final ResponseFuture future = methodData.invocationStrategy.request(methodData.serializationStrategy, classLoader, method, args, baos);
    // toBuffer() is better than toByteArray() since it avoids an
    // array copy.
    final Buffer command = baos.toBuffer();
    // Update the field size.
    BufferEditor editor = command.buffer().bigEndianEditor();
    editor.writeInt(command.length);
