The PIUsers collection represents a list of users from a particular PI server. Depending on where it is obtained from, the collection has different contents. The PIUsers collection obtained from a Server object represents all users on the PI server. A PIUsers collection obtained from a PIGroup contains only those users on a PI server that belong to the particular group.
The PIUsers and PIGroups collections and the PIUser and PIGroup objects are typically used by applications that are designed to manage a PI servers user base.
This object supports the IRefresh and the IPISecurity interfaces.
