The IGISResource interface is an integral part of the Web ADF Common Data Source API. It is implemented by all resource interfaces and implementation classes. This interface defines the generic methods and properties to create functionalities, check if a functionality is supported by a resource, get a reference to the data source, and get the collection of functionalities associated with a resource.



As a developer, you may decide to use Common API interfaces to utilize data sources, resources and functionalities in an agnostic fashion. This means you can work with generic interfaces to do work instead of data source implementations of the Common API.



As a custom data source developer, you may choose to implement the Common API interfaces to create a custom data source with resources and functionalities that can be used by the Web ADF controls.

For more discussion of GIS resources and functionalities, see the topic Working with the Common Data Source API in the Developer Help (also available online at the ArcGIS Resource Center).
