Examples of org.apache.thrift7.transport.TIOStreamTransport

org.apache.thrift7.TException
This is the most commonly used base transport. It takes an InputStream and an OutputStream and uses those to perform all transport operations. This allows for compatibility with all the nice constructs Java already has to provide a variety of types of streams.

      buffer_ = ByteBuffer.allocate(4);


      frameTrans_ = new TMemoryInputTransport();
      response_ = new TByteArrayOutputStream();
      inTrans_ = inputTransportFactory_.getTransport(frameTrans_);
      outTrans_ = outputTransportFactory_.getTransport(new TIOStreamTransport(response_));
      inProt_ = inputProtocolFactory_.getProtocol(inTrans_);
      outProt_ = outputProtocolFactory_.getProtocol(outTrans_);


      if (eventHandler_ != null) {
        context_ = eventHandler_.createContext(inProt_, outProt_, selectionKey);
