3.22.1 Abstract Data Model

  • Article

This section describes a conceptual model of possible data organization that an implementation maintains to participate in this protocol. The described organization is provided to facilitate the explanation of how the protocol behaves. This document does not mandate that implementations adhere to this model as long as their external behavior is consistent with that described in this document.

An IUpdateCollection server maintains the following data elements:

  • Locale: An LCID identifying the locale for localized data.

  • ReadOnly: A VARIANT_BOOL that indicates whether the list is read-only. Once initialized, this data element is not modified.

  • List: An ordered list of IUpdate instances. This data element can be modified only if the collection is not read-only.

  • Count: An integer count of the items in the list. This element can be modified only if the collection is not read-only.
