werkzeug.local._ProxyLookup

class documentation

class _ProxyLookup: (source)

Known subclasses: werkzeug.local._ProxyIOp

Descriptor that handles proxied attribute lookup for :class:`LocalProxy`. :param f: The built-in function this attribute is accessed through. Instead of looking up the special method, the function call is redone on the object. :param fallback: Return this function if the proxy is unbound instead of raising a :exc:`RuntimeError`. :param is_attr: This proxied name is an attribute, not a function. Call the fallback immediately to get the value. :param class_value: Value to return when accessed from the ``LocalProxy`` class directly. Used for ``__doc__`` so building docs still works.

Method	`__call__`	Support calling unbound methods from the class. For example, this happens with ``copy.copy``, which does ``type(x).__copy__(x)``. ``type(x)`` can't be proxied, so it returns the proxy type and descriptor.
