Package users Description

Contains all the classes for managing users and their capabilities.

Users are managed by UserManagers. UserManagers will also maintain a list of users currently associated (or in UserManager terminology "logged on") to an Object.

Users are represented by User objects. You can subclass these to provide for application dependent user information like statistics and the like. By default users will have a name, a password and a set of capabilities.

Capabilities are used to grant or deny users certain rights. You must implement the Capability interface or subclass AbstractCapability to cater for your application specific rights.

In addition to the core classes mentioned above, there are some helper and convenience classes in the package.
