  XEP-0079 Advanced Message Processing

## Stanza elements

class slixmpp.plugins.xep_0079.stanza.AMP(xml=None, parent=None)
  add_rule(action, condition, value)
  del_per_hop()
  get_from()
  get_per_hop()
  get_to()
  interfaces: ClassVar[set[str]] = {'from', 'per_hop', 'status', 'to'}

    The set of keys that the stanza provides for accessing and manipulating the underlying XML object. This set may be augmented with the `plugin_attrib` value of any registered stanza plugins.

  name: ClassVar[str] = 'amp'

    The XML tag name of the element, not including any namespace prefixes. For example, an `ElementBase` object for `<message />` would use `name = 'message'`.

  namespace: str = 'http://jabber.org/protocol/amp'

    The XML namespace for the element. Given `<foo xmlns="bar" />`, then `namespace = "bar"` should be used. The default namespace is `jabber:client` since this is being used in an XMPP library.

  plugin_attrib: ClassVar[str] = 'amp'

    For `ElementBase` subclasses which are intended to be used as plugins, the `plugin_attrib` value defines the plugin name. Plugins may be accessed by using the `plugin_attrib` value as the interface. An example using `plugin_attrib = 'foo'`:

        register_stanza_plugin(Message, FooPlugin)
        msg = Message()
        msg['foo']['an_interface_from_the_foo_plugin']

  plugin_attrib_map: ClassVar[dict[str, type[ElementBase]]] = {'rule': <class 'slixmpp.plugins.xep_0079.stanza.Rule'>, 'rules': <class 'slixmpp.xmlstream.stanzabase.multifactory.<locals>.Multi'>}

    A mapping of the `plugin_attrib` values of registered plugins to their respective classes.

  plugin_iterables: ClassVar[set[type[ElementBase]]] = {<class 'slixmpp.plugins.xep_0079.stanza.Rule'>}

    The set of stanza classes that can be iterated over using the ‘substanzas’ interface. Classes are added to this set when registering a plugin with `iterable=True`:

        register_stanza_plugin(DiscoInfo, DiscoItem, iterable=True)

    Added in version 1.0-Beta5.

  plugin_overrides: ClassVar[dict[str, str]] = {}

    A map of interface operations to the overriding functions. For example, after overriding the `set` operation for the interface `body`, `plugin_overrides` would be:

        {'set_body': <some function>}

  plugin_tag_map: ClassVar[dict[str, type[ElementBase]]] = {'{http://jabber.org/protocol/amp}rule': <class 'slixmpp.plugins.xep_0079.stanza.Rule'>, '{jabber:client}stanza': <class 'slixmpp.xmlstream.stanzabase.multifactory.<locals>.Multi'>}

    A mapping of root element tag names (in `'{namespace}elementname'` format) to the plugin classes responsible for them.

  set_from(value)
  set_per_hop(value)
  set_to(value)

class slixmpp.plugins.xep_0079.stanza.AMPFeature(xml=None, parent=None)
  name: ClassVar[str] = 'amp'

    The XML tag name of the element, not including any namespace prefixes. For example, an `ElementBase` object for `<message />` would use `name = 'message'`.

  namespace: str = 'http://jabber.org/features/amp'

    The XML namespace for the element. Given `<foo xmlns="bar" />`, then `namespace = "bar"` should be used. The default namespace is `jabber:client` since this is being used in an XMPP library.

class slixmpp.plugins.xep_0079.stanza.FailedRule(xml=None, parent=None)
  namespace: str = 'http://jabber.org/protocol/amp#errors'

    The XML namespace for the element. Given `<foo xmlns="bar" />`, then `namespace = "bar"` should be used. The default namespace is `jabber:client` since this is being used in an XMPP library.

class slixmpp.plugins.xep_0079.stanza.FailedRules(xml=None, parent=None)
  name: ClassVar[str] = 'failed-rules'

    The XML tag name of the element, not including any namespace prefixes. For example, an `ElementBase` object for `<message />` would use `name = 'message'`.

  namespace: str = 'http://jabber.org/protocol/amp#errors'

    The XML namespace for the element. Given `<foo xmlns="bar" />`, then `namespace = "bar"` should be used. The default namespace is `jabber:client` since this is being used in an XMPP library.

  plugin_attrib: ClassVar[str] = 'failed_rules'

    A mapping of the `plugin_attrib` values of registered plugins to their respective classes.

  plugin_iterables: ClassVar[set[type[ElementBase]]] = {<class 'slixmpp.plugins.xep_0079.stanza.FailedRule'>}

    The set of stanza classes that can be iterated over using the ‘substanzas’ interface. Classes are added to this set when registering a plugin with `iterable=True`:

        register_stanza_plugin(DiscoInfo, DiscoItem, iterable=True)

    Added in version 1.0-Beta5.

  plugin_overrides: ClassVar[dict[str, str]] = {}

    A map of interface operations to the overriding functions. For example, after overriding the `set` operation for the interface `body`, `plugin_overrides` would be:

  name: ClassVar[str] = 'invalid-rules'

    The XML tag name of the element, not including any namespace prefixes. For example, an `ElementBase` object for `<message />` would use `name = 'message'`.

  namespace: str = 'http://jabber.org/protocol/amp'

    The XML namespace for the element. Given `<foo xmlns="bar" />`, then `namespace = "bar"` should be used. The default namespace is `jabber:client` since this is being used in an XMPP library.

  plugin_attrib: ClassVar[str] = 'invalid_rules'

    For `ElementBase` subclasses which are intended to be used as plugins, the `plugin_attrib` value defines the plugin name. Plugins may be accessed by using the `plugin_attrib` value as the interface. An example using `plugin_attrib = 'foo'`:

        register_stanza_plugin(Message, FooPlugin)
        msg = Message()
        msg['foo']['an_interface_from_the_foo_plugin']

  plugin_attrib_map: ClassVar[dict[str, type[ElementBase]]] = {'rule': <class 'slixmpp.plugins.xep_0079.stanza.Rule'>, 'rules': <class 'slixmpp.xmlstream.stanzabase.multifactory.<locals>.Multi'>}

    A mapping of the `plugin_attrib` values of registered plugins to their respective classes.

  plugin_iterables: ClassVar[set[type[ElementBase]]] = {<class 'slixmpp.plugins.xep_0079.stanza.Rule'>}

    The set of stanza classes that can be iterated over using the ‘substanzas’ interface. Classes are added to this set when registering a plugin with `iterable=True`:

        register_stanza_plugin(DiscoInfo, DiscoItem, iterable=True)

    Added in version 1.0-Beta5.

  plugin_overrides: ClassVar[dict[str, str]] = {}

    A map of interface operations to the overriding functions. For example, after overriding the `set` operation for the interface `body`, `plugin_overrides` would be:

  interfaces: ClassVar[set[str]] = {'action', 'condition', 'value'}

    The set of keys that the stanza provides for accessing and manipulating the underlying XML object. This set may be augmented with the `plugin_attrib` value of any registered stanza plugins.

  name: ClassVar[str] = 'rule'

    The XML tag name of the element, not including any namespace prefixes. For example, an `ElementBase` object for `<message />` would use `name = 'message'`.

  namespace: str = 'http://jabber.org/protocol/amp'

    The XML namespace for the element. Given `<foo xmlns="bar" />`, then `namespace = "bar"` should be used. The default namespace is `jabber:client` since this is being used in an XMPP library.

        msg['foo']['an_interface_from_the_foo_plugin']

  plugin_multi_attrib: ClassVar[str] = 'rules'

    For `ElementBase` subclasses that are intended to be an iterable group of items, the `plugin_multi_attrib` value defines an interface for the parent stanza which returns the entire group of matching substanzas. So the following are equivalent:

        # Given stanza class Foo, with plugin_multi_attrib = 'foos'
        parent['foos']
        filter(isinstance(item, Foo), parent['substanzas'])
