================
|
|
|
|

|
|
|
|
.. function:: Proxy.get_interface_type(self)
|
|
|
|
Binds :c:func:`wp_proxy_get_interface_type`
|
|
|
|
:param self: the proxy
|
|
:returns: the proxy type, the proxy type version
|
|
:rtype: string, integer
|
|
|
|
PipeWire Object
|
|
...............
|
|
|
|
Lua objects that bind a :ref:`WpPipewireObject <pipewire_object_api>`
|
|
contain the following methods:
|
|
|
|
.. function:: PipewireObject.iterate_params(self, param_name)
|
|
|
|
Binds :c:func:`wp_pipewire_object_enum_params_sync`
|
|
|
|
:param self: the proxy
|
|
:param string param_name: the PipeWire param name to enumerate,
|
|
ex "Props", "Route"
|
|
:returns: the available parameters
|
|
:rtype: Iterator; the iteration items are `Spa Pod <lua_spa_pod>`_ objects
|
|
|
|
.. function:: PipewireObject.set_params(self, param_name, pod)
|
|
|
|
Binds :c:func:`wp_pipewire_object_set_param`
|
|
|
|
:param self: the proxy
|
|
:param string param_name: The PipeWire param name to set, ex "Props", "Route"
|
|
:param Pod pod: A Spa Pod object containing the new params
|
|
|
|
Global Proxy
|
|
............
|
|
|
|
Lua objects that bind a :ref:`WpGlobalProxy <global_proxy_api>`
|
|
contain the following methods:
|
|
|
|
.. function:: GlobalProxy.request_destroy(self)
|
|
|
|
Binds :c:func:`wp_global_proxy_request_destroy`
|
|
|
|
:param self: the proxy
|
|
|
|
PipeWire Node
|
|
.............
|
|
|
|
Lua objects that bind a :ref:`WpNode <node_api>` contain the following methods:
|
|
|
|
.. function:: Node.send_command(self, command)
|
|
|
|
Binds :c:func:`wp_node_send_command`
|
|
|
|
:param self: the proxy
|
|
:param string command: the command to send to the node (ex "Suspend")
|
|
|
|
|
|
PipeWire Client
|
|
...............
|
|
|
|
Lua objects that bind a :ref:`WpClient <client_api>`
|
|
contain the following methods:
|
|
|
|
.. function:: Client.update_permissions(self, perms)
|
|
|
|
Binds :c:func:`wp_client_update_permissions`
|
|
|
|
Takes a table where the keys are object identifiers and the values are
|
|
permission strings.
|
|
|
|
Valid object identifiers are:
|
|
|
|
- A number, meaning the bound ID of a proxy
|
|
- The string "any" or the string "all", which sets the default permissions
|
|
for this client
|
|
|
|
The permission strings have a chmod-like syntax (ex. "rwx" or "r-xm"), where:
|
|
|
|
- "r" means permission to read the object
|
|
- "w" means permission to write data to the object
|
|
- "x" means permission to call methods on the object
|
|
- "m" means permission to set metadata for the object
|
|
- "-" is ignored and can be used to make the string more readable when
|
|
a permission flag is omitted
|
|
|
|
**Example:**
|
|
|
|
.. code-block:: lua
|
|
|
|
client:update_permissions {
|
|
["all"] = "r-x",
|
|
[35] = "rwxm",
|
|
}
|
|
|
|
:param self: the proxy
|
|
:param table perms: the permissions to update for this client
|
|
|

|
|
|

|
.. function:: Metadata.iterate(self, subject)
|
|
|
|
Binds :c:func:`wp_metadata_new_iterator`
|
|
|
|
:param self: the proxy
|
|
:param integer subject: the subject id
|
|
:returns: an iterator
