| aoqi@0 | 33 | * {@link PropertySet} that combines properties exposed from multiple |
| aoqi@0 | 34 | * {@link PropertySet}s into one. |
| aoqi@0 | 35 | * |
| aoqi@0 | 36 | * <p> |
| aoqi@0 | 37 | * This implementation allows one {@link PropertySet} to assemble |
| aoqi@0 | 38 | * all properties exposed from other "satellite" {@link PropertySet}s. |
| aoqi@0 | 39 | * (A satellite may itself be a {@link DistributedPropertySet}, so |
| aoqi@0 | 40 | * in general this can form a tree.) |
| aoqi@0 | 41 | * |
| aoqi@0 | 42 | * <p> |
| aoqi@0 | 43 | * This is useful for JAX-WS because the properties we expose to the application |
| aoqi@0 | 44 | * are contributed by different pieces, and therefore we'd like each of them |
| aoqi@0 | 45 | * to have a separate {@link PropertySet} implementation that backs up |
| aoqi@0 | 46 | * the properties. For example, this allows FastInfoset to expose its |
| aoqi@0 | 47 | * set of properties to {@link RequestContext} by using a strongly-typed fields. |
| aoqi@0 | 48 | * |
| aoqi@0 | 49 | * <p> |
| aoqi@0 | 50 | * This is also useful for a client-side transport to expose a bunch of properties |
| aoqi@0 | 51 | * into {@link ResponseContext}. It simply needs to create a {@link PropertySet} |
| aoqi@0 | 52 | * object with methods for each property it wants to expose, and then add that |
| aoqi@0 | 53 | * {@link PropertySet} to {@link Packet}. This allows property values to be |
| aoqi@0 | 54 | * lazily computed (when actually asked by users), thus improving the performance |
| aoqi@0 | 55 | * of the typical case where property values are not asked. |
| aoqi@0 | 56 | * |
| aoqi@0 | 57 | * <p> |
| aoqi@0 | 58 | * A similar benefit applies on the server-side, for a transport to expose |
| aoqi@0 | 59 | * a bunch of properties to {@link WebServiceContext}. |
| aoqi@0 | 60 | * |
| aoqi@0 | 61 | * <p> |
| aoqi@0 | 62 | * To achieve these benefits, access to {@link DistributedPropertySet} is slower |
| aoqi@0 | 63 | * compared to {@link PropertySet} (such as get/set), while adding a satellite |
| aoqi@0 | 64 | * object is relatively fast. |
