P-Index (Java Platform SE 6) (original) (raw)

as of JDK version 1.4 -- Replaced by java.security.Policy. java.security.Policy has a method:

    public PermissionCollection getPermissions
        (java.security.ProtectionDomain pd)

and ProtectionDomain has a constructor:

    public ProtectionDomain
        (CodeSource cs,
         PermissionCollection permissions,
         ClassLoader loader,
         Principal[] principals)

These two APIs provide callers the means to query the Policy for Principal-based Permission entries.
