1.46 +/**
1.47 + * {@link PropertySet} that combines properties exposed from multiple
1.48 + * {@link PropertySet}s into one.
1.49 + *
1.50 + * <p>
1.51 + * This implementation allows one {@link PropertySet} to assemble
1.52 + * all properties exposed from other "satellite" {@link PropertySet}s.
1.53 + * (A satellite may itself be a {@link DistributedPropertySet}, so
1.54 + * in general this can form a tree.)
1.55 + *
1.56 + * <p>
1.57 + * This is useful for JAX-WS because the properties we expose to the application
1.58 + * are contributed by different pieces, and therefore we'd like each of them
1.59 + * to have a separate {@link PropertySet} implementation that backs up
1.60 + * the properties. For example, this allows FastInfoset to expose its
1.61 + * set of properties to {@link RequestContext} by using a strongly-typed fields.
1.62 + *
1.63 + * <p>
1.64 + * This is also useful for a client-side transport to expose a bunch of properties
1.65 + * into {@link ResponseContext}. It simply needs to create a {@link PropertySet}
1.66 + * object with methods for each property it wants to expose, and then add that
1.67 + * {@link PropertySet} to {@link Packet}. This allows property values to be
1.68 + * lazily computed (when actually asked by users), thus improving the performance
1.69 + * of the typical case where property values are not asked.
1.70 + *
1.71 + * <p>
1.72 + * A similar benefit applies on the server-side, for a transport to expose
1.73 + * a bunch of properties to {@link WebServiceContext}.
1.74 + *
1.75 + * <p>
1.76 + * To achieve these benefits, access to {@link DistributedPropertySet} is slower
1.77 + * compared to {@link PropertySet} (such as get/set), while adding a satellite
1.78 + * object is relatively fast.
