v2 v3 28 28 == Motivation == 29 29 30 Currently method MgFeatureService:: CreateFeatureSource() supports creating a SDF feature source only. It is really a limitation of Feature Service. This RFC will extend this method to support all file based feature sources.30 Currently method MgFeatureService::!CreateFeatureSource() supports creating a SDF feature source only. It is really a limitation of Feature Service. This RFC will extend this method to support all file based feature sources. 31 31 32 32 == Proposed Solution == 33 33 34 ==== MgFileFeatureSourceParams ====35 36 A new class MgFileFeatureSourceParams is added to represent parameters which are used to create a file-based feature source. The existing class MgCreateSdfParams inherits from it. Previously MgCreateSdfParams inherits from virtual base classMgFeatureSourceParams directly as shown in the following picture.37 38 The class definition of MgFileFeatureSourceParams is as follows.34 ==== !MgFileFeatureSourceParams ==== 35 36 A new class !MgFileFeatureSourceParams is added to represent parameters which are used to create a file-based feature source. The existing class !MgCreateSdfParams inherits from it. Previously !MgCreateSdfParams inherits from virtual base class !MgFeatureSourceParams directly as shown in the following picture. 37 38 The class definition of !MgFileFeatureSourceParams is as follows. 39 39 40 40 {{{ 41 /////////////////////////////////////////////// 41 42 /// \brief 42 /// Contains the parameters used to create an file-based feature source. 43 /// Contains the parameters used to create an file-based 44 /// feature source. 43 45 /// 44 46 class MgFileFeatureSourceParams : public MgFeatureSourceParams … … 48 50 /// \brief 49 51 /// Constructs an empty MgFileFeatureSourceParams object. 50 ///51 /// The FDO provider name of the feature source.52 /// 53 /// The FDO provider name of the feature source. 52 54 /// \param spatialContextName (String/string) 53 55 MgFileFeatureSourceParams (CREFSTRING providerName); 54 56 55 57 /////////////////////////////////////////////// 56 ///brief58 ///brief 57 59 /// Constructs an MgFileFeatureSourceParams object with the supplied 58 /// parameters.60 /// parameters. 59 61 /// \param providerName (String/string) 60 /// FDO provider name of the feature source to be created.62 /// FDO provider name of the feature source to be created. 61 63 /// \param spatialContextName (String/string) 62 /// The name of the spatial context.
