deprecate_pybind11()

def lsst.utils.deprecated.deprecate_pybind11	(		obj,
			reason,
			version,
			category = FutureWarning
	)

Deprecate a pybind11-wrapped C++ interface function, method or class.

This needs to use a pass-through Python wrapper so that
`~deprecated.sphinx.deprecated` can update its docstring; pybind11
docstrings are native and cannot be modified.

Note that this is not a decorator; its output must be assigned to
replace the method being deprecated.

Parameters
----------
obj : function, method, or class
    The function, method, or class to deprecate.
reason : `str`
    Reason for deprecation, passed to `~deprecated.sphinx.deprecated`
version : 'str'
    Next major version in which the interface will be deprecated,
    passed to `~deprecated.sphinx.deprecated`
category : `Warning`
    Warning category, passed to `~deprecated.sphinx.deprecated`

Returns
-------
obj : function, method, or class
    Wrapped function, method, or class

Examples
--------
.. code-block:: python

   ExposureF.getCalib = deprecate_pybind11(ExposureF.getCalib,
           reason="Replaced by getPhotoCalib. (Will be removed in 18.0)",
           version="17.0", category=FutureWarning))

suppress_deprecations()

def lsst.utils.deprecated.suppress_deprecations

(

category = FutureWarning

)

Suppress warnings generated by `deprecated.sphinx.deprecated`.

Naively, one might attempt to suppress these warnings by using
`~warnings.catch_warnings`. However, `~deprecated.sphinx.deprecated`
attempts to install its own filter, overriding that. This convenience
method works around this and properly suppresses the warnings by providing
a mock `~warnings.simplefilter` for `~deprecated.sphinx.deprecated` to
call.

Parameters
----------
category : `Warning` or subclass
    The category of warning to suppress.
