Provider Capabilities
[Feature Service]
Provider Capabilities
The MgFeatureService API delegates much of its functionality to FDO providers. The providers implement the storage and retrieval of feature data from a variety of RDBMS and file-based datastore technologies.
A set of provider capabilities has been defined, and each provider has been characterized according to what capabilities it supports. For example, the FDO Provider for Oracle supports the creation, description, and destruction of a schema definition, but the FDO Provider for ArcSDE supports only the description of a schema definition.
The capabilities are grouped in the following categories:
- Connection
- Schema
- Commands
- Expressions
- Filters
- Raster
- Topology
The MgFeatureService::GetCapabilities method returns an XML representation of a provider's capabilities. See FdoProviderCapabilities for the definition of the XML representation.
The capability characterization can be used to execute code conditionally depending on the provider being used and what capability is being executed.
Example (C#)
The GetFeatureProviders method cyles through the list of provider names and creates a FeatureProvider object for each one.
The FeatureProvider constructor uses the MgFeatureService object to get the capabilities for the provider. The capabilities are in xml and the Extract methods use xpath expressions to extract the capability values from the xml.
The utility methods show the use of System Xml classes to extract values from the xml.
Here are a few of the capability strings generated by this code for the SDF provider.
- ConnectionCapabilities:ThreadCapability=PerConnectionThreaded;SpatialContextExtentType=Dynamic;
- CommandCapabilities:Commands=+Select+Insert+Delete+Update+DescribeSchema+ApplySchema+CreateSpatialContext+GetSpatialContexts+SelectAggregates;SelectExpressions;SelectFunctions;SelectDistinct;
- SchemaCapabilities:ClassType=+Class+FeatureClass;DataType=+Boolean+Byte+DateTime+Decimal+Double+Int16+Int32+Int64+Single+String;Inheritance;AssociationProperties;AutoIdGeneration;SupportedAutoGeneratedTypes=+Int32;SchemaModification;
- GeometryCapabilities:GeometryTypes=+Point+LineString+Polygon+MultiPoint+MultiLineString+MultiPolygon+MultiGeometry+CurveString+CurvePolygon+MultiCurveString+MultiCurvePolygon;ComponentType=+LinearRing+ArcSegment+LinearSegment+CurveRing;Dimensionality=XYZM;
- FilterCapabilities:ConditionType=+Comparison+Like+In+Null+Spatial;SpatialOperation=+Contains+Disjoint+Intersects+Within+Inside+EnvelopeIntersects;DistanceOperation=;
- ExpressionCapabilities:ExpressionType=+Basic+Function;FunctionDefinitions=+Concat+SpatialExtents+Ceil+Floor+Lower+Upper+Sum+Count+Min+Avg+Max;

The constructor takes a provider name, a file handle, and an MgByteReader containing the provider capabilities. The provider name is obtained from MgFeatureService::GetFeatureProviders. The provider capabilities is obtained from MgFeatureService::GetCapabilities. The file handle is for logging.
