Each interface, say foo, may be overridden in three ways:
set_foo
get_foo
del_foo
To declare an override in a plugin, add the class field
overrides as so:
overrides = ['set_foo', 'del_foo']
Each override must have a matching set_foo(), etc method
for implementing the new behaviour.
To enable the overrides for a particular parent stanza,
pass the option overrides=True to register_stanza_plugin.
register_stanza_plugin(Stanza, Plugin, overrides=True)
Example code:
class Test(ElementBase):
name = 'test'
namespace = 'testing'
interfaces = set(('foo', 'bar'))
sub_interfaces = set(('bar',))
class TestOverride(ElementBase):
name = 'test-override'
namespace = 'testing'
plugin_attrib = 'override'
interfaces = set(('foo',))
overrides = ['set_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, value):
print("overrides!")
self.parent()._set_attr('foo', 'override-%s' % value)
register_stanza_plugin(Test, TestOverride, overrides=True)
Example usage:
>>> t = TestStanza()
>>> t['foo'] = 'bar'
>>> t['foo']
'override-bar'
