Usage

From source file:io.airlift.drift.transport.netty.server.ThriftServerHandler.java

private ListenableFuture<ThriftFrame> decodeMessage(ChannelHandlerContext context, TTransport messageData,
        Transport transport, Protocol protocol, Map<String, String> headers, boolean supportOutOfOrderResponse)
        throws Exception {
    long start = System.nanoTime();
    TProtocolReader protocolReader = protocol.createProtocol(messageData);

    TMessage message = protocolReader.readMessageBegin();
    Optional<MethodMetadata> methodMetadata = methodInvoker.getMethodMetadata(message.getName());
    if (!methodMetadata.isPresent()) {
        return immediateFuture(writeApplicationException(context, message.getName(), transport, protocol,
                message.getSequenceId(), supportOutOfOrderResponse, UNKNOWN_METHOD,
                "Invalid method name: '" + message.getName() + "'", null));
    }// w  ww  .j av a  2  s .  c o  m
    MethodMetadata method = methodMetadata.get();

    if (message.getType() != TMessageType.CALL && message.getType() != TMessageType.ONEWAY) {
        return immediateFuture(writeApplicationException(context, message.getName(), transport, protocol,
                message.getSequenceId(), supportOutOfOrderResponse, INVALID_MESSAGE_TYPE,
                "Invalid method message type: '" + message.getType() + "'", null));
    }

    Map<Short, Object> parameters = readArguments(method, protocolReader);

    ListenableFuture<Object> result = methodInvoker
            .invoke(new ServerInvokeRequest(method, headers, parameters));
    methodInvoker.recordResult(message.getName(), start, result);
    return FluentFuture.from(result).transformAsync(value -> {
        try {
            return immediateFuture(writeSuccessResponse(context, method, transport, protocol,
                    message.getSequenceId(), supportOutOfOrderResponse, value));
        } catch (Exception e) {
            return immediateFailedFuture(e);
        }
    }, directExecutor()).withTimeout(requestTimeout.toMillis(), MILLISECONDS, timeoutExecutor)
            .catchingAsync(Exception.class, exception -> {
                try {

                            message.getSequenceId(), supportOutOfOrderResponse, exception));

                    return immediateFailedFuture(e);
                }
            }, directExecutor());
