   Type functionalityType
)

Parameters

functionalityType

The Type of functionality to check, e.g., IQueryFunctionality. Use an interface that derives from IGISFunctionality.

Return Value

GIS resources support varying types of functionality to perform services such as querying, geocoding, geoprocessing, creating a scalebar, and returning map tiles. Not all resources support the same functionalities. You can work with functionalities by using the CreateFunctionality method to obtain the functionality object. Before requesting a particular functionality, you should generally use SupportsFunctionality() check to ensure the functionality is supported by the resource.

To check functionality, pass the interface for the functionality type, such as IQueryFunctionality. If the functionality is supported, you can use CreateFunctionality to obtain the functionality object. Typically you can work with the functionality in a generic way on the interface level, rather than declaring and working with the particular resource implementation.

Types of functionality that are used most frequently include:

• Query functionality (IQueryFunctionality)
• Geocode functionality (IGeocodeFunctionality)
• Geoprocessing functionality (IGeoprocessingFunctionality)

For more information on resource functionalities, see the topic Working with resources and functionalities in the Developer Help.
