__init__(self,
context=None,
do_enter_exit=False,
**kwargs)
(Constructor)
| source code
|
Create a State object for use in with
statements.
When entering the with statement, the properties of
context given in kwargs will be set to their
respective values. On exiting the with statement, the old
value will be restored.
If context defines __enter__ and
__exit__ methods, this will be called on entering and
exiting the with block, respectively, if
do_enter_exit is True.
No guarantee is made about the order in which the properties are set,
but they are guaranteed to be reset in reverse order.
For convenience, __getattr__ and __setattr__
calls are redirected to context, so that with
State(...) as x: works as expected.
- Parameters:
context (Context or any other object with attributes) - The context object on which to set the properties, or the current
context if it is None.do_enter_exit (bool) - Whether to call context's __enter__ and
__exit__ methods.kwargs (dict) - A dictionary of property names and their values. - Overrides:
object.__init__
