示例1: GetFeatureClassByMap

	FeatureClass* DescribeFeatureTypeHandler::GetFeatureClassByMap(WebRequest* pWebRequest, WebContext* pWebContext, User* pUser)
	{
		const char* typeName = NULL;
		Layer* pLayer = NULL;
		GLogger *pLogger = augeGetLoggerInstance();
		DescribeFeatureTypeRequest* pRequest = static_cast<DescribeFeatureTypeRequest*>(pWebRequest);
		typeName = pRequest->GetTypeName();
		
		const char* mapName = pRequest->GetMapName();
		if(mapName==NULL)
		{
			GError* pError = augeGetErrorInstance();
			pError->SetError("No Map is attached");
			return NULL;
		}

		CartoManager* pCartoManager = augeGetCartoManagerInstance();
		Map *pMap = pCartoManager->LoadMap(pUser->GetID(), mapName);
		if(pMap==NULL)
		{
			char msg[AUGE_MSG_MAX];
			g_sprintf(msg, "Cannot load map [%s]", mapName);
			GError* pError = augeGetErrorInstance();
			pError->SetError(msg);
			return NULL;
		}

		pLayer = pMap->GetLayer(typeName);
		if(pLayer==NULL)
		{
