XEP-0231: Bits of Binary

class slixmpp.plugins.xep_0231.XEP_0231(xmpp, config=None)

XEP-0231 Bits of Binary

del_bob(cid)

Delete a stored BoB. :rtype: Future

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

dependencies: ClassVar[Set[str]] = {'xep_0030'}

Some plugins may depend on others in order to function properly. Any plugin names included in dependencies will be initialized as needed if this plugin is enabled.

description: str = 'XEP-0231: Bits of Binary'

A longer name for the plugin, describing its purpose. For example, a plugin for XEP-0030 would use ‘Service Discovery’ as its description value.

async get_bob(jid=None, cid=None, cached=True, ifrom=None, **iqkwargs)

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.

Parameters:

• 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:

Iq

name: str = 'xep_0231'

A short name for the plugin based on the implemented specification. For example, a plugin for XEP-0030 would use ‘xep_0030’.

async set_bob(data, mtype, cid=None, max_age=None)

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.

Parameters:

• 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:

str

Returns:

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.

set_bob

• jid: JID sending the bob

• node: unused

• ifrom: JID receiving the bob

• args: BitsOfBinary element.

Set a BoB in the cache.

get_bob

• 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.

del_bob

• jid: unused

• node: unused

• ifrom: JID sending the bob

• args: str content-id of the bob

Delete a BoB from the cache.

Stanza elements

del_data()

get_data()

get_max_age()

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.

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.

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()
msg['foo']['an_interface_from_the_foo_plugin']

set_data(value)

set_max_age(value)
