public interface RoleMapper
The RoleMapper
interface defines the security service provider interface (SSPI) for objects capable of obtaining the appropriate set of roles for a particular resource that has been granted to a specific subject.
An implementation of the RoleMapper
interface is the part of a Role Mapping provider that must return a role as a form of principal. Implementations are free to extend the format of a role beyond that of a principal to include other representations such as permissions or permission collections.
A Role Mapping provider can utilize the ContextHandler
interface to retrieve other information about the context of the request in which it is called, such as the value of parameters. A Role Mapping provider must know the names of the parameters and the data types of the associated values in order to utilize this feature. If the value of the handler
parameter is null
, this indicates that the caller was unwilling or unable to provide access to additional information.
A Role Mapping provider must implement the two built-in groups: "users" and "everyone". All subjects are members of the "everyone" group and all non-anonymous subjects (that is, subjects with one or more principals) are members of the "users" group.
