Explicit Interface Implementations

	Name	Description
	_Attribute.GetIDsOfNames	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)

Remarks

For more information and examples, see Rules Propagate Changes Within the Model.

The type of rule is determined by its base class. For example, AddRule, ChangeRule, DeleteRule.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
