List of all members.

Public Member Functions
STRING	GetCoordinateSystemWkt ()
	Gets the well-known text description of the coordinate system.
MgFeatureSchema *	GetFeatureSchema ()
	Gets the feature schema definition.
STRING	GetFileName ()
	Gets the file name to be created. For SHP FDO provider, it is used to get path name because multiple files will be created if there are multiple feature classes in the specified featue schame.
virtual STRING	GetProviderName ()
	Gets the FDO provider name of the feature source.
STRING	GetSpatialContextDescription ()
	Gets the spatial context description.
STRING	GetSpatialContextName ()
	Gets the user-defined spatial context name.
double	GetXYTolerance ()
	Gets the tolerance used for the X and Y ordinates.
double	GetZTolerance ()
	Gets the tolerance for the Z ordinate.
	MgFileFeatureSourceParams ()
	Constructs an empty MgFileFeatureSourceParams object.
	MgFileFeatureSourceParams (CREFSTRING providerName)
	Constructs an MgFileFeatureSourceParams object with the specified FDO provider name.
	MgFileFeatureSourceParams (CREFSTRING providerName, CREFSTRING spatialContextName, CREFSTRING srsWkt, MgFeatureSchema *featureSchema)
	Constructs an MgFileFeatureSourceParams object with the supplied parameters.

Detailed Description

Contains the parameters used to create a file-based feature source.

Remarks:

Use MgFeatureService::DescribeSchema and MgFeatureService::GetSpatialContexts to get the values needed to construct and configure the MgFileFeatureSourceParams object.

Only file-based FDO providers that support the FdoICreateDataStore command can be used with this class to create Feature Sources. As of this writing, the known supported file-based FDO providers are:

• OSGeo.SDF
• OSGeo.SHP
• OSGeo.SQLite

You cannot create non-file Feature Sources using this class

Example (PHP)

 $schemaCollection = $featureService->DescribeSchema($activeFeatSrcResId, $schemaName, NULL);
 $schema = $schemaCollection->GetItem(0);
 $activeOnly = true;
 $activeSpatialContextReader = $featureService->GetSpatialContexts($activeFeatSrcResId, $activeOnly);
 $activeSpatialContextReader->ReadNext();
 $spatialContextName = $activeSpatialContextReader->GetName();
 $coordSysWkt = $activeSpatialContextReader->GetCoordinateSystemWkt();
 $providerName = "OSGeo.SDF";
 $createSdfParams = new MgFileFeatureSourceParams($providerName, $spatialContextName, $coordSysWkt, $schema);
 $createSdfParams->SetSpatialContextDescription($activeSpatialContextReader->GetDescription());
 $createSdfParams->SetXYTolerance($activeSpatialContextReader->GetXYTolerance());
 $createSdfParams->SetZTolerance($activeSpatialContextReader->GetZTolerance());
