25 |  |
      * Classes that implement this interface can act as a broker for
26 |  |
      * <code>Initable</code> classes.
27 |  |
      *
28 |  |
      * Functionality provided by the broker includes:
29 |  |
      *
30 |  |
      * <ul>
31 |  |
      *
32 |  |
      * <li>Maintaining a single instance of each <code>Initable</code> in
33 |  |
      * the system.</li>
34 |  |
      *
35 |  |
      * <li>Early initialization of <code>Initables</code> during system
36 |  |
      * startup.</li>
37 |  |
      *
38 |  |
      * <li>Late initialization of <code>Initables</code> before they are
39 |  |
      * used.</li>
40 |  |
      *
41 |  |
      * <li>Providing instances of <code>Initables</code> to requesting
42 |  |
      * parties.</li>
43 |  |
      *
44 |  |
      * <li>Maintainging dependencies between <code>Initables</code> during
45 |  |
      * early initalization phases, including circular dependencies
46 |  |
      * detection.</li>
47 |  |
