Om - * communication takes place over two distinct bands: control band and - * notification band.</p> - * <p>The control band is where clients send commands, and receive a simple - * response, either OK or an error.</p> - * <p>All notifications of engine state (ie new nodes) are sent over the - * notification band <em>which is seperate from the control band</em>. The - * reasoning behind this is that many clients may be connected at the same - * time - a client may receive notifications that are not a direct consequence - * of some message it sent.</p> - * <p>The notification band can be thought of as a stream of events representing - * the changing engine state. For example, It is possible for a client to send - * commands and receive aknowledgements, and not listen to the notification band - * at all; or (in the near future anyway) for a client to use UDP for the control - * band (for speed), and TCP for the notification band (for reliability and - * order guarantees).</p> - * \n\n - */ - - -/* Documentation for namespace portion implemented in Responder.cpp */ - -/** \page client_osc_namespace - * \n - * <h3>Notification Band</h3> - */ - -/** \page client_osc_namespace - * <p> \b /om/response/ok - Respond successfully to a user command - * \arg \b responder-id (int) - Responder ID this is a response to - * </p> \n \n - */ - -/** \page client_osc_namespace - * <p> \b /om/response/error - Respond negatively to a user command - * \arg \b responder-id (int) - Request ID this is a response to - * \arg \b message (string) - Error message (natural language text) - * </p> \n \n - */ - - - -/** \page client_osc_namespace - * \n - * <h3>Notification Band</h3> - */ - -/** \page client_osc_namespace - * <p> \b /om/error - Notification that an error has occurred - * \arg \b message (string) - Error message (natural language text) - * - * \li This is for notification of errors that aren't a direct response to a - * user command, ie "unexpected" errors.</p> \n \n - */ -void -OSCClient::error(const string& msg) -{ - lo_send(_address, "/om/error", "s", msg.c_str()); -} - - -/** \page client_osc_namespace - * <p> \b /om/num_plugins - * \arg \b num (int) - Number of plugins engine has loaded - * \li This is sent before sending the list of plugins, so the client is aware - * of how many plugins (/om/plugin messages) to expect.</p> \n \n - */ - - -/** \page client_osc_namespace - * <p> \b /om/num_plugins - * \arg \b num (int) - Number of plugins engine has loaded - * \li This is sent before sending the list of plugins, so the client is aware - * of how many plugins (/om/plugin messages) to expect.</p> \n \n - */ -void -OSCClient::num_plugins(uint32_t num) -{ - lo_message m = lo_message_new(); - lo_message_add_int32(m, num); - lo_send_message(_address, "/om/num_plugins", m); -} - - -/** \page client_osc_namespace - * <p> \b /om/plugin - Notification of the existance of a plugin - * \arg \b type (string) - Type if plugin ("LADSPA", "DSSI", or "Internal") - * \arg \b uri (string) - URI of the plugin (see engine namespace documentation) \n - * \arg \b lib-name (string) - Name of shared library plugin resides in (ie "cmt.so") - * \arg \b plug-label (string) - Label of the plugin (ie "dahdsr_iaoa") - * \arg \b name (string) - Descriptive human-readable name of plugin (ie "ADSR Envelope") - * </p> \n \n - */ -/* -void -OSCClient::plugins() -{ - om->node_factory()->lock_plugin_list(); - - const list<Plugin*>& plugs = om->node_factory()->plugins(); - const Plugin* plugin; - - lo_timetag tt; - lo_timetag_now(&tt); - lo_bundle b = lo_bundle_new(tt); - lo_message m = lo_message_new(); - list<lo_message> msgs; - - lo_message_add_int32(m, plugs.size()); - lo_bundle_add_message(b, "/om/num_plugins", m); - msgs.push_back(m); - - for (list<Plugin*>::const_iterator j = plugs.begin(); j != plugs.end(); ++j) { - plugin = (*j); - m = lo_message_new(); - - lo_message_add_string(m, plugin->type_string()); - lo_message_add_string(m, plugin->uri().c_str()); - lo_message_add_string(m, plugin->plug_label().c_str()); - lo_message_add_string(m, plugin->name().c_str()); - lo_bundle_add_message(b, "/om/plugin", m); - msgs.push_back(m); - if (lo_bundle_length(b) > 1024) { - lo_send_bundle(_address, b); - lo_bundle_free(b); - b = lo_bundle_new(tt); - } - } - - if (lo_bundle_length(b) > 0) { - lo_send_bundle(_address, b); - lo_bundle_free(b); - } else { - lo_bundle_free(b); - } - for (list<lo_bundle>::const_iterator i = msgs.begin(); i != msgs.end(); ++i) - lo_message_free(*i); - - om->node_factory()->unlock_plugin_list(); -} -*/ - -/** \page client_osc_namespace - * <p> \b /om/new_node - Notification of a new node's creation. - * \arg \b plug-uri (string) - URI of the plugin new node is an instance of - * \arg \b path (string) - Path of the new node - * \arg \b polyphonic (integer-boolean) - Node is polyphonic (1 = yes, 0 = no) - * \arg \b num-ports (integer) - Number of ports (number of new_port messages to expect) - * \li New nodes are sent as a bundle.
