aoqi@0 39 * Proxy transport {@link Tube} and {@link Pipe} that lazily determines the
aoqi@0 40 * actual transport pipe by looking at {@link Packet#endpointAddress}.
aoqi@0 41 *
aoqi@0 42 * <p>
aoqi@0 43 * This pseudo transport is used when there's no statically known endpoint address,
aoqi@0 44 * and thus it's expected that the application will configure {@link BindingProvider}
aoqi@0 45 * at runtime before making invocation.
aoqi@0 46 *
aoqi@0 47 * <p>
aoqi@0 48 * Since a typical application makes multiple invocations with the same endpoint
aoqi@0 49 * address, this class implements a simple cache strategy to avoid re-creating
aoqi@0 50 * transport pipes excessively.
