Make extending stanza objects nicer.
A stanza object may add is_extension = True to its class definition
to provide a single new interface to a parent stanza.
For example:
import sleekxmpp
from sleekxmpp import Iq
from sleekxmpp.xmlstream import ElementBase, register_stanza_plugin, ET
class Foo(ElementBase):
"""
Test adding just an attribute to a parent stanza.
Adding subelements works as expected.
"""
is_extension = True
interfaces = set(('foo',))
plugin_attrib = 'foo'
def setup(self, xml):
# Don't include an XML element in the parent stanza
# since we're adding just an attribute.
# If adding a regular subelement, no need to do this.
self.xml = ET.Element('')
def set_foo(self, val):
self.parent()._set_attr('foo', val)
def get_foo(self):
return self.parent()._get_attr('foo')
def del_foo(self):
self.parent()._del_attr('foo')
register_stanza_plugin(Iq, Foo)
i1 = Iq()
i2 = Iq(xml=ET.fromstring("<iq xmlns='jabber:client' foo='bar' />"))
>>> i1['foo'] = '3'
>>> i1
'3'
>>> i1
'<iq id="0" foo="3" />'
>>> i2
'<iq id="0" foo="bar" />'
>>> i2['foo']
'bar'
>>> del i2['foo']
>>> i2
'<iq id="0" />'
