| def | fromkeys (cls, iterable, value=None) |
A `dict`-like `~collections.abc.MutableMapping` for use when sharing a
map between C++ and Python.
For compatibility with C++, ``SimpleGenericMap`` has the following
restrictions:
- all keys must be of the same type
- values must be built-in types or subclasses of
`lsst.afw.typehandling.Storable`. Almost any user-defined class in
C++ or Python can have `~lsst.afw.typehandling.Storable` as a mixin.
As a safety precaution, `~lsst.afw.typehandling.Storable` objects that are
added from C++ may be copied when you retrieve them from Python, making it
impossible to modify them in-place. This issue does not affect objects that
are added from Python, or objects that are always passed by
:cpp:class:`shared_ptr` in C++.
Parameters
----------
mapping : `collections.abc.Mapping`, optional
iterable : iterable, optional
dtype : `type`, optional
The type of key the map accepts. Not required if ``mapping`` or
``iterable`` is provided.
**kwargs
Aside from the ``dtype`` keyword, a ``SimpleGenericMap`` takes the same
input arguments as `dict`.
