IADsClass

The IADsClass interface enables a COM object to provide current schema class definitions for the type of Active Directory objects that can be created in a directory service. IADsClass, IADsProperty, and IADsSyntax make up the interfaces available on schema management objects to view and modify definitions for the schema class objects that define a directory service, including interfaces, properties, methods, containment relationships, and provider-specific rules.

Properties accessed by IADsClass are defined on the ADSI Schema Class Object.

Names of schema classes are those identified through the IADs::get_Schema method. Don't confuse the schema class name with the system CLSID class identifier property which indicates the COM object that implements this COM class.

When to Implement

Implement IADsClass when you are providing an Active Directory implementation for your directory service, or when you are adding functionality to an already existing provider implementation. If your directory service does not support extensible schemas, create an ADSI Schema Container Object that has properties that cannot be modified.

When to Use

Call the methods on IADsClass when you are browsing the ADSI Schema Container Objects in a schema container. These methods define which types of schema classes can contain or be contained by other schema class types. Call these methods whenever you access information about the type of schema object an Active Directory object is. The IADsClass:get_PrimaryInterface method identifies the IID for the interface that QueryInterface uses at run-time to determine whether an object is of a specific schema class.
