XEP-0231: Bits of Binary#

class slixmpp.plugins.xep_0231.XEP_0231(xmpp, config=None)[source]#

XEP-0231 Bits of Binary


Delete a stored BoB.

Changed in version 1.8.0: This function now returns a Future.

Return type


async get_bob(jid=None, cid=None, cached=True, ifrom=None, **iqkwargs)[source]#

Get a BOB.

Changed in version 1.8.0: Results not in cache do not raise an error when cached is True. This function is now a coroutine.

  • jid (Optional[JID]) – JID to fetch the BOB from.

  • cid (Optional[str]) – Content ID (actually required).

  • cached (bool) – To fetch the BOB from the local cache first (from CID only)

Return type


async set_bob(data, mtype, cid=None, max_age=None)[source]#

Register a blob of binary data as a BOB.

Changed in version 1.8.0: If max_age is specified, the registered data will be destroyed after that time. This function is now a coroutine.

  • data (bytes) – Data to register.

  • mtype (str) – Mime Type of the data (e.g. image/jpeg).

  • cid (Optional[str]) – Content-ID (will be auto-generated if left out).

  • max_age (Optional[int]) – Duration of content availability.

Return type



The cid value.

Internal API methods#

The default API handlers for this plugin manage an in-memory cache of bits of binary by content-id.

  • jid: JID sending the bob

  • node: unused

  • ifrom: JID receiving the bob

  • args: BitsOfBinary element.

Set a BoB in the cache.

  • jid: JID receiving the bob

  • node: unused

  • ifrom: JID sending the bob

  • args: str content-id of the bob

  • returns: BitsOfBinary element.

Get a BoB from the cache.

  • jid: unused

  • node: unused

  • ifrom: JID sending the bob

  • args: str content-id of the bob

Delete a BoB from the cache.

Stanza elements#

class slixmpp.plugins.xep_0231.stanza.BitsOfBinary(xml=None, parent=None)[source]#
interfaces: ClassVar[Set[str]] = {'cid', 'data', 'max_age', 'type'}#

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.

iterables: List[ElementBase]#

A list of child stanzas whose class is included in plugin_iterables.

loaded_plugins: Set[str]#
name: ClassVar[str] = 'data'#

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 = 'urn:xmpp:bob'#

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.

parent: Optional[ReferenceType[ElementBase]]#

A weakref.weakref to the parent stanza, if there is one. If not, then parent is None.

plugin_attrib: ClassVar[str] = 'bob'#

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()
plugins: Dict[Tuple[str, Optional[str]], ElementBase]#

An ordered dictionary of plugin stanzas, mapped by their plugin_attrib value.

tag: str#

The name of the tag for the stanza’s root element. It is the same as calling tag_name() and is formatted as '{namespace}elementname'.

xml: ET.Element#

The underlying XML object for the stanza. It is a standard xml.etree.ElementTree object.
