Class JndiPermissionCollection

java.lang.Object

java.security.PermissionCollection

org.jboss.naming.JndiPermissionCollection

All Implemented Interfaces:

java.io.Serializable

final class JndiPermissionCollection
extends java.security.PermissionCollection
implements java.io.Serializable

A JndiPermissionCollection stores a set of JndiPermission permissions. JndiPermission objects must be stored in a manner that allows them to be inserted in any order, but enable the implies function to evaluate the implies method. For example, if you have two JndiPermissions:

1. "/tmp/-", "bind"
2. "/tmp/scratch/foo", "unbind"

And you are calling the implies function with the JndiPermission: "/tmp/scratch/foo", "bind,unbind", then the implies function must take into account both the /tmp/- and /tmp/scratch/foo permissions, so the effective permission is "bind,unbind".
