zope.security.proxy.isinstance(object, cls)[source]

Test whether an object is an instance of a type.

This works even if the object is security proxied:

>>> from zope.security.proxy import isinstance
>>> class C1(object):
...     pass

>>> c = C1()
>>> isinstance(c, C1)
True

>>> from zope.security.checker import ProxyFactory
>>> isinstance(ProxyFactory(c), C1)
True

>>> class C2(C1):
...     pass

>>> c = C2()
>>> isinstance(c, C1)
True

>>> from zope.security.checker import ProxyFactory
>>> isinstance(ProxyFactory(c), C1)
True
