Description

Globally unique identifier enquiry. Each contact item has a unique identifier, stored as a descriptor. It is referred to as the "UID string". It is a combination of the unique identifier of the database in which the contact item was created, the contact item ID and the date/time of the contact item's creation. This class provides a single static exported function to enquire whether an item was created in a specified database.
