zope.security.proxy.isinstance(object, cls)

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

zope.security.proxy.Proxy

alias of zope.security.proxy.ProxyPy

class zope.security.proxy.ProxyPy(value, checker)

Bases: zope.proxy.PyProxyBase

The pure-Python reference implementation of a security proxy.

This should normally not be created directly, instead use the ProxyFactory().

You can choose to use this implementation instead of the C implementation by default by setting the PURE_PYTHON environment variable before zope.security is imported.
