Class Direction

java.lang.Object
  weblogic.security.spi.Direction

public final class Direction
extends Object

The 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.

ONCE

public static final Direction ONCE

Indicates that the authorization check is being performed once, with no indication of whether it is being done before or after an operation. (Implementation details determine when the authorization check is performed.) Currently, containers only call the isAccessAllowed method using a Direction of ONCE.

PRIOR

public static final Direction PRIOR

Indicates that the authorization check is being performed prior to allowing the request to be processed.

POST

public static final Direction POST

Indicates that the authorization check is being peformed after the request has been allowed to be processed, but before the results have been returned.
