C++ (Cpp) jargs Examples

Example #1

File: iotjs_module_buffer.cpp Project: no-problemo/iotjs

JObject CreateBuffer(size_t len) {
  JObject jglobal(JObject::Global());
  IOTJS_ASSERT(jglobal.IsObject());

  JObject jBuffer(jglobal.GetProperty("Buffer"));
  IOTJS_ASSERT(jBuffer.IsFunction());

  JArgList jargs(1);
  jargs.Add(JVal::Number((int)len));

  JResult jres(jBuffer.Call(JObject::Null(), jargs));
  IOTJS_ASSERT(jres.IsOk());
  IOTJS_ASSERT(jres.value().IsObject());

  return jres.value();
}

Example #2

File: iotjs_module_tcp.cpp Project: 0-T-0/iotjs

void OnRead(uv_stream_t* handle, ssize_t nread, const uv_buf_t* buf) {
  TcpWrap* tcp_wrap = reinterpret_cast<TcpWrap*>(handle->data);
  IOTJS_ASSERT(tcp_wrap != NULL);

  // tcp handle
  JObject jtcp = tcp_wrap->jobject();
  IOTJS_ASSERT(jtcp.IsObject());

  // socket object
  JObject jsocket = jtcp.GetProperty("owner");
  IOTJS_ASSERT(jsocket.IsObject());

  // onread callback
  JObject jonread = jtcp.GetProperty("onread");
  IOTJS_ASSERT(jonread.IsFunction());

  JArgList jargs(4);
  jargs.Add(jsocket);
  jargs.Add(JVal::Number((int)nread));
  jargs.Add(JVal::Bool(false));

  if (nread <= 0) {
    if (buf->base != NULL) {
      ReleaseBuffer(buf->base);
    }
    if (nread < 0) {
      if (nread == UV__EOF) {
        jargs.Set(2, JVal::Bool(true));
      }
      MakeCallback(jonread, JObject::Null(), jargs);
    }
    return;
  }

  JObject jbuffer(CreateBuffer(static_cast<size_t>(nread)));
  BufferWrap* buffer_wrap = BufferWrap::FromJBuffer(jbuffer);

  buffer_wrap->Copy(buf->base, nread);

  jargs.Add(jbuffer);
