BEA WebLogic Server 9.0 API Reference

weblogic.security.spi
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.
