Class PermissionHeuristic

java.lang.Object
  edu.internet2.middleware.grouper.permissions.PermissionHeuristic

public class PermissionHeuristic
extends java.lang.Object

 this takes a permissions assignment (PermissionEntry), and 
 gives it a score so you can find the best entry, even if it is 
 a tie, to decide if allow or deny.
 
 Max depth resource: 30 (configurable in grouper.properties)
 
 (864000) person/role assignment
 
 (432000) direct role assignment (14400 * 30)
 
 (14400) role assignment with role depth 29
 
 (7200) assignment to user as opposed to group

 (3600) direct resource assignment (120*30)
 
 (120) indirect direct resource assignment depth 29

 (60) direct action assignment (2*30)

 (58) action depth 1

 (56) action depth 2

 (54) action depth 3

 (2) action depth 29

 (1) allow
