can limit the liability of the programmer or help prevent accidental security vulnerabilities because it helps prevent the method that calls from being used to access the resource protected by the denied permission. If a method calls on a permission, and if a Demand for that permission is invoked by a caller lower in the call stack, that security check will fail when it reaches the .
is ignored for a permission not granted because a demand for that permission will not succeed.Notes to Inheritors
