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