public interface SessionAttributes

This interface defines the methods that classes with SessionAttributes functionalities have to implement.

A SessionAttributes class defines the context in which a session is being validated. The presence and the value of certain attributes can influence whether the access to a secured resource is authorized or prohibited for a particular user.

For example, regular users have access to everything besides ithe administration interface. Resources that are restricted to administrators can for example have a role attribute that is set to admin. A SessionValidator instance can detect the presence of this attribute and act accordingly to verify if the user has the authorities of the required role (in this case, administrator rights).
