Parameters ---------- argument_extractor : ArgumentExtractorType A callable which extracts the dispatchable arguments. Extracted arguments should be marked by the :obj:`Dispatchable` class. It has the same signature as the desired multimethod. argument_replacer : ArgumentReplacerType A callable with the signature (args, kwargs, dispatchables), which should also return an (args, kwargs) pair with the dispatchables replaced inside the args/kwargs. domain : str A string value indicating the domain of this multimethod. default: Optional[Callable], optional The default implementation of this multimethod, where ``None`` (the default) specifies there is no default implementation. Examples -------- In this example, ``a`` is to be dispatched over, so we return it, while marking it as an ``int``. The trailing comma is needed because the args have to be returned as an iterable. >>> def override_me(a, b): ... return Dispatchable(a, int), Next, we define the argument replacer that replaces the dispatchables inside args/kwargs with the supplied ones. >>> def override_replacer(args, kwargs, dispatchables): ... return (dispatchables[0], args[1]), {} Next, we define the multimethod. >>> overridden_me = generate_multimethod( ... override_me, override_replacer, "ua_examples" ... ) Notice that there's no default implementation, unless you supply one. >>> overridden_me(1, "a") Traceback (most recent call last): ... uarray.BackendNotImplementedError: ... >>> overridden_me2 = generate_multimethod( ... override_me, override_replacer, "ua_examples", default=lambda x, y: (x, y) ... ) >>> overridden_me2(1, "a") (1, 'a') See Also -------- uarray See the module documentation for how to override the method by creating backends. ) get_defaultsr functoolsupdate_wrapper)rPrQrRrS kw_defaults arg_defaultsoptsua_funcs r.rrsDB'33E&F#Kt G  # #G @@r=Fc[R"5nURUSX4$![a 0UlO[a Of=f[ XU5nX@RUSX4'U$)a A context manager that sets the preferred backend.

Implies ``only``. only: bool Whether or not this should be the last backend to try. See Also -------- set_backend: For when you know which backend to set Notes ----- Support is determined by the ``__ua_convert__`` protocol. Backends not supporting the type must return ``NotImplemented`` from their ``__ua_convert__`` if they don't support input of that type. Examples -------- Suppose we have two backends ``BackendA`` and ``BackendB`` each supporting different types, ``TypeA`` and ``TypeB``. Neither supporting the other type: >>> with ua.set_backend(ex.BackendA): ... ex.call_multimethod(ex.TypeB(), ex.TypeB()) Traceback (most recent call last): ... uarray.BackendNotImplementedError: ...

Parameters ---------- dispatchables: Sequence[Union[uarray.Dispatchable, Any]] The dispatchables that must be supported domain: string The domain to query for backends and set. coerce: bool Whether or not to allow coercion to the backend's types. Implies ``only``. only: bool Whether or not this should be the last backend to try. dispatch_type: Optional[Any] The default dispatch type associated with ``dispatchables``, aka ":ref:`marking `". See Also -------- determine_backend: For a single dispatch value set_backend: For when you know which backend to set Notes ----- Support is determined by the ``__ua_convert__`` protocol. Backends not supporting the type must return ``NotImplemented`` from their ``__ua_convert__`` if they don't support input of that type. Examples -------- :func:`determine_backend` allows the backend to be set from a single object. :func:`determine_backend_multi` allows multiple objects to be checked simultaneously for support in the backend. Suppose we have a ``BackendAB`` which supports ``TypeA`` and ``TypeB`` in the same call, and a ``BackendBC`` that doesn't support ``TypeA``. >>> with ua.set_backend(ex.BackendAB), ua.set_backend(ex.BackendBC): ... a, b = ex.TypeA(), ex.TypeB() ... with ua.determine_backend_multi( ...

We can also use leave out the ``ua.Dispatchable`` if we specify the default ``dispatch_type`` for the ``dispatchables`` argument. >>> with ua.set_backend(ex.BackendAB), ua.set_backend(ex.BackendBC): ... a, b = ex.TypeA(), ex.TypeB() ... with ua.determine_backend_multi( ...
