"""Establish the containment of the object in the container
The object and necessary event are returned. The object may be a
`ContainedProxy` around the original object. The event is an added
event, a moved event, or None.
If the object implements `IContained`, simply set its `__parent__`
and `__name__` attributes:
>>> container = {}
>>> item = Contained()
>>> x, event = containedEvent(item, container, u'foo')
>>> x is item
True
>>> item.__parent__ is container
True
>>> item.__name__
u'foo'
We have an added event:
>>> event.__class__.__name__
'ObjectAddedEvent'
>>> event.object is item
True
>>> event.newParent is container
True
>>> event.newName
u'foo'
>>> event.oldParent
>>> event.oldName
Now if we call contained again:
>>> x2, event = containedEvent(item, container, u'foo')
>>> x2 is item
True
>>> item.__parent__ is container
True
>>> item.__name__
u'foo'
We don't get a new added event:
>>> event
If the object already had a parent but the parent or name was
different, we get a moved event:
>>> x, event = containedEvent(item, container, u'foo2')
>>> event.__class__.__name__
'ObjectMovedEvent'
>>> event.object is item
True
>>> event.newParent is container
True
>>> event.newName
u'foo2'
>>> event.oldParent is container
True
>>> event.oldName
u'foo'
If the `object` implements `ILocation`, but not `IContained`, set it's
`__parent__` and `__name__` attributes *and* declare that it
implements `IContained`:
>>> from zope.app.location import Location
>>> item = Location()
>>> IContained.providedBy(item)
False
>>> x, event = containedEvent(item, container, 'foo')
>>> x is item
True
>>> item.__parent__ is container
True
>>> item.__name__
'foo'
>>> IContained.providedBy(item)
True
If the `object` doesn't even implement `ILocation`, put a
`ContainedProxy` around it:
>>> item = []
>>> x, event = containedEvent(item, container, 'foo')
>>> x is item
False
>>> x.__parent__ is container
True
>>> x.__name__
'foo'
Make sure we don't lose existing directly provided interfaces.
>>> from zope.interface import Interface, directlyProvides
>>> class IOther(Interface):
... pass
>>> from zope.app.location import Location
>>> item = Location()
>>> directlyProvides(item, IOther)
>>> IOther.providedBy(item)
True
>>> x, event = containedEvent(item, container, 'foo')
>>> IOther.providedBy(item)
True
