const char* OGR_FD_GetName(OGRFeatureDefnH hDefn) Get name of the OGRFeatureDefn passed as an argument. This function is the same as the C++ method OGRFeatureDefn::GetName(). Parameters: ----------- hDefn: handle to the feature definition to get the name from. the name. This name is internal and should not be modified, or freed.
|
int OGR_FD_GetFieldCount(OGRFeatureDefnH hDefn) Fetch number of fields on the passed feature definition. This function is the same as the C++ OGRFeatureDefn::GetFieldCount(). Parameters: ----------- hDefn: handle to the feature definition to get the fields count from. count of fields.
|
GetFieldDefn(self, int i) -> FieldDefn OGRFieldDefnH OGR_FD_GetFieldDefn(OGRFeatureDefnH hDefn, int iField) Fetch field definition of the passed feature definition. This function is the same as the C++ method OGRFeatureDefn::GetFieldDefn(). Starting with GDAL 1.7.0, this method will also issue an error if the index is not valid. Parameters: ----------- hDefn: handle to the feature definition to get the field definition from. iField: the field to fetch, between 0 and GetFieldCount()-1. an handle to an internal field definition object or NULL if invalid index. This object should not be modified or freed by the application. |
GetFieldIndex(self, char name) -> int int OGR_FD_GetFieldIndex(OGRFeatureDefnH hDefn, const char *pszFieldName) Find field by name. The field index of the first field matching the passed field name (case insensitively) is returned. This function is the same as the C++ method OGRFeatureDefn::GetFieldIndex. Parameters: ----------- hDefn: handle to the feature definition to get field index from. pszFieldName: the field name to search for. the field index, or -1 if no match found. |
AddFieldDefn(self, FieldDefn defn) void OGR_FD_AddFieldDefn(OGRFeatureDefnH hDefn, OGRFieldDefnH hNewField) Add a new field definition to the passed feature definition. To add a new field definition to a layer definition, do not use this function directly, but use OGR_L_CreateField() instead. This function should only be called while there are no OGRFeature objects in existance based on this OGRFeatureDefn. The OGRFieldDefn passed in is copied, and remains the responsibility of the caller. This function is the same as the C++ method OGRFeatureDefn::AddFieldDefn(). Parameters: ----------- hDefn: handle to the feature definition to add the field definition to. hNewField: handle to the new field definition. |
OGRwkbGeometryType OGR_FD_GetGeomType(OGRFeatureDefnH hDefn) Fetch the geometry base type of the passed feature definition. This function is the same as the C++ method OGRFeatureDefn::GetGeomType(). Parameters: ----------- hDefn: handle to the feature definition to get the geometry type from. the base type for all geometry related to this definition.
|
SetGeomType(self, OGRwkbGeometryType geom_type) void OGR_FD_SetGeomType(OGRFeatureDefnH hDefn, OGRwkbGeometryType eType) Assign the base geometry type for the passed layer (the same as the feature definition). All geometry objects using this type must be of the defined type or a derived type. The default upon creation is wkbUnknown which allows for any geometry type. The geometry type should generally not be changed after any OGRFeatures have been created against this definition. This function is the same as the C++ method OGRFeatureDefn::SetGeomType(). Parameters: ----------- hDefn: handle to the layer or feature definition to set the geometry type to. eType: the new type to assign. |
int OGR_FD_GetReferenceCount(OGRFeatureDefnH hDefn) Fetch current reference count. This function is the same as the C++ method OGRFeatureDefn::GetReferenceCount(). Parameters: ----------- hDefn: hanlde to the feature definition on witch OGRFeature are based on. the current reference count.
|
int OGR_FD_IsGeometryIgnored(OGRFeatureDefnH hDefn) Determine whether the geometry can be omitted when fetching features. This function is the same as the C++ method OGRFeatureDefn::IsGeometryIgnored(). Parameters: ----------- hDefn: hanlde to the feature definition on witch OGRFeature are based on. ignore state
|
SetGeometryIgnored(self, int bIgnored) void OGR_FD_SetGeometryIgnored(OGRFeatureDefnH hDefn, int bIgnore) Set whether the geometry can be omitted when fetching features. This function is the same as the C++ method OGRFeatureDefn::SetGeometryIgnored(). Parameters: ----------- hDefn: hanlde to the feature definition on witch OGRFeature are based on. bIgnore: ignore state |
int OGR_FD_IsStyleIgnored(OGRFeatureDefnH hDefn) Determine whether the style can be omitted when fetching features. This function is the same as the C++ method OGRFeatureDefn::IsStyleIgnored(). Parameters: ----------- hDefn: handle to the feature definition on which OGRFeature are based on. ignore state
|
SetStyleIgnored(self, int bIgnored) void OGR_FD_SetStyleIgnored(OGRFeatureDefnH hDefn, int bIgnore) Set whether the style can be omitted when fetching features. This function is the same as the C++ method OGRFeatureDefn::SetStyleIgnored(). Parameters: ----------- hDefn: hanlde to the feature definition on witch OGRFeature are based on. bIgnore: ignore state |
Once called, self has effectively been destroyed. Do not access. For backwards compatiblity only |
