我有两个表,它们都包含一个环境表
table Environment {
windDirection:int = 0;
windMagnitude:int = 0;
windVariation:int = 0;
rain:ushort = 0;
snow:ushort = 0;
dust:ushort = 0;
fog:ushort = 0;
}
table REQUEST_SCENARIO_CHANGE_ENVIRONMENT_M {
scenarioId:string;
environment:Environment;
}
enum SCENARIO_CHANGE_ENVIRONMENT_RESULT_E : byte {
SUCCESS,
CLIENT_DOESNT_CONTROL_SCENARIO,
SCENARIO_NOT_IN_FREE_MODE, // scenario was not setup-free'd
SCENARIO_NOT_FOUND,
UNKNOWN_FAILURE
}
table RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M {
result:SCENARIO_CHANGE_ENVIRONMENT_RESULT_E;
environment:Environment;
}
顾名思义,第一个表是由许多控制客户端中的一个发出的请求并发送到服务器。服务器以错误代码(结果)响应。如果结果是成功,则将 RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M 发送给所有客户端。这样,如果环境成功地改变了一个,每个人都会注意到这一事实。
我的问题是,由于我在创建 RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M 的代码中已经有一个正确填充的环境对象,是否可以采取
var message = Message.GetRootAsMessage(Utilities.ByteBuffer(data.Data));
var request = REQUEST_SCENARIO_CHANGE_ENVIRONMENT_M.GetRootAsREQUEST_SCENARIO_CHANGE_ENVIRONMENT_M(Utilities.ByteBuffer(message.GetPayloadBytes()));
SCENARIO_CHANGE_ENVIRONMENT_RESULT_E result = SCENARIO_CHANGE_ENVIRONMENT_RESULT_E.UNKNOWN_FAILURE;
Scenario scenario = GetScenarioFromId(request.ScenarioId);
if (scenario == null)
{
result = SCENARIO_CHANGE_ENVIRONMENT_RESULT_E.SCENARIO_NOT_FOUND;
}
else
{
if (!scenario.IsController(message.SessionToken))
{
result = SCENARIO_CHANGE_ENVIRONMENT_RESULT_E.CLIENT_DOESNT_CONTROL_SCENARIO;
}
else if (scenario.EndScenario() == STS_ERRORS.ERR_NO_ERROR)
{
// TODO: Unit Test
result = SCENARIO_CHANGE_ENVIRONMENT_RESULT_E.SUCCESS;
}
else
{
// TODO: Unit Test
result = SCENARIO_CHANGE_ENVIRONMENT_RESULT_E.UNKNOWN_FAILURE;
}
}
FlatBuffers.FlatBufferBuilder fbb = new FlatBuffers.FlatBufferBuilder(1024);
IOSServer.IOSCore.Messages.Environment.StartEnvironment(fbb);
RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M.StartRESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M(fbb);
RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M.AddResult(fbb, result);
RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M.AddEnvironment(fbb, request.Environment);
var response = RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M.EndRESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M(fbb);
fbb.Finish(response.Value);
// If the scenario is not able to be ended. Only respond to the originator
if (result != SCENARIO_CHANGE_ENVIRONMENT_RESULT_E.SUCCESS)
{
EventData responseData = new EventData(Utilities.GetMessageBytes(fbb, DataType.RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M, Utilities.UniqueId(), 0, message.RequestId));// TODO: Timestamp
Mediator.GetInstance().RaiseEvent(responseData);
}
else // Otherwise, send to all scenario members
{
EventData responseData = new EventData(Utilities.GetMessageBytes(fbb, DataType.RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M, Utilities.UniqueId()));// TODO: Timestamp
Mediator.GetInstance().RaiseEvent(responseData, sendToAllExternalClients: true);
_scenarios.Remove(request.ScenarioId);
}
问题是
RESPONSE_SCENARIO_CHANGE_ENVIRONMENT_M.AddEnvironment(fbb, request.Environment);
是否有可能得到一个FlatBuffers.Offset<Environment>
from Environment
?
