MgCreateSdfParams Class Reference
[MgCreateSdfParams]

Inherits MgFeatureSourceParams.

List of all members.

Detailed Description

Contains the parameters used to create an SDF feature source.

Remarks:
Use MgFeatureService::DescribeSchema and MgFeatureService::GetSpatialContexts to get the values needed to construct and configure the MgCreateSdfParams object.
Example (PHP) 
 $schemaCollection = $featureService->DescribeSchema($activeFeatSrcResId, $schemaName);
 $schema = $schemaCollection->GetItem(0);
 $activeOnly = true;
 $activeSpatialContextReader = $featureService->GetSpatialContexts($activeFeatSrcResId, $activeOnly);
 $activeSpatialContextReader->ReadNext();
 $spatialContextName = $activeSpatialContextReader->GetName();
 $coordSysWkt = $activeSpatialContextReader->GetCoordinateSystemWkt();
 $createSdfParams = new MgCreateSdfParams($spatialContextName, $coordSysWkt, $schema);
 $createSdfParams->SetSpatialContextDescription($activeSpatialContextReader->GetDescription());
 $createSdfParams->SetXYTolerance($activeSpatialContextReader->GetXYTolerance());
 $createSdfParams->SetZTolerance($activeSpatialContextReader->GetZTolerance());
