21 * construct an arbitrary method from a dispatch table found by looking
22 * up a match for the < operation_id, name, property > combination.
23 * constructor and destructor are the constructor and destructor for that
26 * These objects are normally cached, unless the provider says not to cache.
27 * However, force_cache can be used to force caching whatever the provider
28 * says (for example, because the application knows better).
