32 * LUR: Local User Registry
\r
34 * Concept by Robert Garskof, Implementation by Jonathan Gathman
\r
36 * Where we can keep local copies of users and roles for faster Authorization when asked.
\r
38 * Note: Author cannot resist the mental image of using a Fishing Lure to this LUR pattern
\r
42 public interface Lur {
\r
44 * Allow the Lur, which has correct Permission access, to create and hand back.
\r
46 public Permission createPerm(String p);
\r
49 * Fish for Principals in a Pond
\r
51 * or more boringly, is the User identified within a named collection representing permission.

\r
59 * Fish all the Principals out a Pond
\r
61 * For additional humor, pronounce the following with a Southern Drawl, "FishOil"
\r
63 * or more boringly, load the List with Permissions found for Principal
\r
65 * @param principalName

71 * Allow implementations to disconnect, or cleanup resources if unneeded

76 * Does this LUR handle this pond exclusively? Important for EpiLUR to determine whether

84 * What domain of User does this LUR support? (used to avoid asking when not possible)
