werkzeug.local._ProxyLookup

class documentation

class _ProxyLookup:

Known subclasses: werkzeug.local._ProxyIOp

Descriptor that handles proxied attribute lookup for LocalProxy.

Parameters
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.
fallback	Return this function if the proxy is unbound instead of raising a `RuntimeError`.
is_attr	This proxied name is an attribute, not a function. Call the fallback immediately to get the value.
class_value	Value to return when accessed from the `LocalProxy` class directly. Used for `__doc__` so building docs still works.

def __call__(self, instance, *args, **kwargs):

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.

Parameters
instance:`LocalProxy`	Undocumented
*args:`t.Any`	Undocumented
**kwargs:`t.Any`	Undocumented
Returns
`t.Any`	Undocumented

def __get__(self, instance, owner=None):

Parameters
instance:`LocalProxy`	Undocumented
owner:`t.Optional[type]`	Undocumented
Returns
`t.Any`	Undocumented
