public abstract class Association
extends Category
Association represents a dynamic collection of child Item(s) related to a parent Item identified by a selector. For example, the user account Item(s) that are related to a group account Item with selector "bar" could be represented by an Association. An Association represents an 1-to-n relationship. A 1-to-1 relationship is handled as a special case of 1-to-n relationship.

Association derives from Category and supports the same client mechanisms for obtaining dynamic information about the Item(s) in an Association instance.

If an Item with the specified parent selector does not exist, the Association will monitor for the addition of an Item with that selector.

If an Item with the specified parent selector existed, but is deleted while a client is monitoring the Association, all Items are removed from the Association and the Association continues monitoring of the system for the addition of an Item with that parent selector.

The actual logic for determining and monitoring Item(s) in an Association resides on the server-side. Clients can obtain a Association instances using HostContext methods.
