Field Detail

USE_DEFAULT_CONSTRAINTS

static final AuthorizationConstraint USE_DEFAULT_CONSTRAINTS

Constant denoting that the runtime's default logic for discovering what AuthorizationConstraint to apply to a request should be used.

Method Detail

getConstraint

AuthorizationConstraint getConstraint(HttpServletRequest request)
                                      throws ServletException,
                                             IOException

Determine the AuthorizationConstraint that applies to a resource.

Parameters:

request - an HttpServletRequest object that contains the request the client has made of the servlet

Returns:

AuthorizationConstraint instance if a constraint applies to the request. null if no constraint applies to the request. USE_DEFAULT_CONSTRAINTS if this method cannot determine what constraint applies to the request, and therefore the runtime's default AuthorizationConstraint discovery logic will be applied to the request.

Throws:

IOException - if an input or output error is detected when the servlet determines the AuthorizationConstraint

ServletException - if the request for the dynamic privilege could not be handled
