/**
 * This interface is implemented by objects that can be used to obtain
 * authentication context configuration objects, that is,
 * ClientAuthConfig or ServerAuthConfig objects.
 *
 * 

* * Authentication context configuration objects serve as sources of * the authentication context objects, that is, ClientAuthContext or * ServerAuthContext objects, for a specific message layer * and messaging context. * *

* * Authentication context objects encapsulate the initialization, * configuration, and invocation of authentication modules, that is, * ClientAuthModule or ServerAuthModule objects, for * a specific message exchange within a specific message layer and * messaging context. * *

* * Callers do not directly operate on authentication modules. * Instead, they rely on a ClientAuthContext or ServerAuthContext * to manage the invocation of modules. A caller obtains an instance * of ClientAuthContext or ServerAuthContext by calling the respective * getAuthContext method on a ClientAuthConfig * or ServerAuthConfig object obtained from an * AuthConfigProvider. * *

* * The following represents a typical sequence of calls for obtaining * a client authentication context object, and then using it to secure * a request. *

    *
  1. AuthConfigProvider provider;
  2. *
  3. ClientAuthConfig config = provider.getClientAuthConfig(layer,appID,cbh);
  4. *
  5. String authContextID = config.getAuthContextID(messageInfo);
  6. *
  7. ClientAuthContext context = config.getAuthContext(authContextID,subject,properties);
  8. *
  9. context.secureRequest(messageInfo,subject);
  10. *
* *

* * Every implementation of this interface must offer a public, * two argument constructor with the following signature: *

 * 
 * public AuthConfigProviderImpl(Map properties, AuthConfigFactory factory);
 * 
 * 
* where the properties argument may be null, and where all values and * keys occurring in a non-null properties argument must be of type String. * When the factory argument is not null, it indicates that the * provider is to self-register at the factory by calling the following * method on the factory: *
 * 
 * public String
 * registerConfigProvider(AuthConfigProvider provider, String layer,
 *                        String appContext, String description);
 * 
 * 
* @version 1.0 * * @see ClientAuthContext * @see ServerAuthContext * @see AuthConfigFactory */ public interface AuthConfigProvider { /** * Get an instance of ClientAuthConfig from this provider. * *

* * The implementation of this method returns a ClientAuthConfig * instance that describes the configuration of ClientAuthModules * at a given message layer, and for use in an identified application * context. * * @param layer A String identifying the message layer * for the returned ClientAuthConfig object. * This argument must not be null. * * @param appContext A String that identifies the messaging context * for the returned ClientAuthConfig object. * This argument must not be null. * * @param handler A CallbackHandler to be passed to the ClientAuthModules * encapsulated by ClientAuthContext objects derived from the * returned ClientAuthConfig. This argument may be null, * in which case the implementation may assign a default handler * to the configuration. * The CallbackHandler assigned to the configuration must support * the Callback objects required to be supported by the profile * of this specification being followed by the messaging runtime. * The CallbackHandler instance must be initialized with any * application context needed to process the required callbacks * on behalf of the corresponding application. * * @return A ClientAuthConfig Object that describes the configuration * of ClientAuthModules at the message layer and messaging context * identified by the layer and appContext arguments. * This method does not return null. * * @exception AuthException If this provider does not support the * assignment of a default CallbackHandler to the returned * ClientAuthConfig. * * @exception SecurityException If the caller does not have permission * to retrieve the configuration. */ public ClientAuthConfig getClientAuthConfig (String layer, String appContext, CallbackHandler handler) throws AuthException; /** * Get an instance of ServerAuthConfig from this provider. * *
