我按照下面的模式存储数据。
namespace iCalendarParser;
table EventParsed {
UID:string;
Organizer:string;
Summary:string;
Description:string;
Attendee:[string];
Categories:string;
DtEnd:string;
DtStart:string;
DtStamp:string;
AttendeeCounter:short;
}
table TableofEvents{
events:[EventParsed];
}
root_type TableofEvents;
我在我的C++应用程序中存储这样的数据。
std::vector<flatbuffers::Offset<flatbuffers::String>> ListOfAttendee;
std::vector<flatbuffers::Offset<iCalendarParser::EventParsed>> ListofEvents;
for (auto EventList : ListofAllEvents)
{
auto Organizer = builder.CreateString(EventList->Organizer);
auto UID = builder.CreateString(EventList->UID);
auto DtStart = builder.CreateString(EventList->DtStart);
auto DtEnd = builder.CreateString(EventList->DtEnd);
auto DtStamp = builder.CreateString(EventList->DtStamp);
auto Summary = builder.CreateString(EventList->Summary);
auto Description = builder.CreateString(EventList->Description);
auto Categories = builder.CreateString(EventList->Categories);
for (int i = 0; i < EventList->AttendeeCounter; i++)
{
ListOfAttendee.push_back(builder.CreateString(EventList->Attendee[i]));
}
auto VectorListofAttendee = builder.CreateVector(ListOfAttendee);
auto CreatEventInFlatBuffer = CreateEventParsed(builder, UID, Organizer, Summary, Description, VectorListofAttendee, Categories, DtEnd, DtStart, DtStamp, EventList->AttendeeCounter);
ListofEvents.push_back(CreatEventInFlatBuffer);
}
auto CreatVectorOfEventInFlatbuffer = builder.CreateVector(ListofEvents);
auto InsertEventInFlatBufferList = CreateTableofEvents(builder,
CreatVectorOfEventInFlatbuffer);
builder.Finish(InsertEventInFlatBufferList);
uint8_t *buf = builder.GetBufferPointer();
int size = builder.GetSize();
std::ofstream ofile("icalBin.bin", std::ios::binary);
ofile.write((char *)&buf, size);
ofile.close();
在我的C应用程序中,我试图访问反序列化数据。
byte[] ReadbytesfromFile = File.ReadAllBytes("icalBin.bin");
var buffer = new ByteBuffer(ReadbytesfromFile);
var tableofEvents = TableofEvents.GetRootAsTableofEvents(buffer);
int len = tableofEvents.EventsLength;
我不知道怎么了。有人能告诉我如何根据模式访问嵌套表并反序列化为C。
总体思路:
1.获取事件列表。
2.访问单个事件结构。(我想得到的结果)
