public final class Direction
extends java.lang.Object
Direction
class is used to represent when the
authorization check is to be performed by an Access Decision
(either before a resource is accessed or after access has been allowed).
Instances are ONCE
, POST
, and PRIOR
.
For example, if the Direction
is PRIOR
and the
resource is a directory, the Access Decision might allow access.
If the Direction
is POST
, the Access Decision
might want to check what is being returned (that is, a particular file might be
returned from a directory that should not be). An Access Decision
might be called ONCE
for access to a resource or it might get called
PRIOR
and then POST
access to a resource. ONCE
and PRIOR
determine if the resource can be accessed; POST
determines if what is being returned from the resource may be returned.
