Detailed Description

Represents a "user group membership" – a specific instance of a user belonging to a group.

For example, the fact that user Mary belongs to the sysop group is a user group membership.

The class encapsulates rows in the user_groups table. The logic is low-level and doesn't run any hooks. Often, you will want to call User::addGroup() or User::removeGroup() instead.

Since: 1.29
