C++ (Cpp) MethodMetadata示例

示例#1

文件： TurboModule.cpp 项目： joshuawatson/react-native

jsi::Value TurboModule::get(jsi::Runtime& runtime, const jsi::PropNameID& propName) {
  std::string propNameUtf8 = propName.utf8(runtime);
  auto p = methodMap_.find(propNameUtf8);
  if (p == methodMap_.end()) {
    throw std::runtime_error("Function '" + propNameUtf8 + "' cannot be found on module: " + name_);
  }
  MethodMetadata meta = p->second;
  return jsi::Function::createFromHostFunction(
    runtime,
    propName,
    meta.argCount,
    [this, meta](facebook::jsi::Runtime &rt, const facebook::jsi::Value &thisVal, const facebook::jsi::Value *args, size_t count) {
      return meta.invoker(rt, *this, args, count);
    });
}
