- public class AuthorizationManagerFactory
- extends java.lang.Object
Factory for creating AuthorizationManager
instances.
An instance is created from a configuration described in an XML file.
The factory may optionally register the newly created instances in a table,
using as key an arbitrary string provided by the calling application.
In this way several applications may share the same instance of
AuthorizationManager, following this model:
- one application creates an instance of AuthorizationManager and associates
it with a given ID;
- the remaining applications requires the instance of AuthorizationManager
associated with the above given ID.
