33 * {@link PropertySet} that combines properties exposed from multiple
34 * {@link PropertySet}s into one.
35 *
36 * <p>
37 * This implementation allows one {@link PropertySet} to assemble
38 * all properties exposed from other "satellite" {@link PropertySet}s.
39 * (A satellite may itself be a {@link DistributedPropertySet}, so
40 * in general this can form a tree.)
41 *
42 * <p>
43 * This is useful for JAX-WS because the properties we expose to the application
44 * are contributed by different pieces, and therefore we'd like each of them
45 * to have a separate {@link PropertySet} implementation that backs up
46 * the properties. For example, this allows FastInfoset to expose its
47 * set of properties to {@link RequestContext} by using a strongly-typed fields.
48 *
49 * <p>
50 * This is also useful for a client-side transport to expose a bunch of properties
51 * into {@link ResponseContext}. It simply needs to create a {@link PropertySet}
52 * object with methods for each property it wants to expose, and then add that
53 * {@link PropertySet} to {@link Packet}. This allows property values to be
54 * lazily computed (when actually asked by users), thus improving the performance
55 * of the typical case where property values are not asked.
56 *
57 * <p>
58 * A similar benefit applies on the server-side, for a transport to expose
59 * a bunch of properties to {@link WebServiceContext}.
60 *
61 * <p>
62 * To achieve these benefits, access to {@link DistributedPropertySet} is slower
63 * compared to {@link PropertySet} (such as get/set), while adding a satellite
64 * object is relatively fast.
