deprecated

(function from pyomo.common.deprecation)

pyomo.common.deprecation.deprecated(msg=None, logger=None, version=None, remove_in=None)

Decorator to indicate that a function, method, or class is deprecated.

This decorator will cause a warning to be logged when the wrapped function or method is called, or when the deprecated class is constructed. This decorator also updates the target object’s docstring to indicate that it is deprecated.

Parameters:

• msg (str) – a custom deprecation message (default: “This {function|class} has been deprecated and may be removed in a future release.”)

• logger (str) – the logger to use for emitting the warning (default: the calling pyomo package, or “pyomo”)

• version (str) – [required] the version in which the decorated object was deprecated. General practice is to set version to the current development version (from pyomo –version) during development and update it to the actual release as part of the release process.

• remove_in (str) – the version in which the decorated object will be removed from the code.

Example

>>> from pyomo.common.deprecation import deprecated
>>> @deprecated(version='1.2.3')
... def sample_function(x):
...     return 2*x
>>> sample_function(5)
WARNING: DEPRECATED: This function (sample_function) has been deprecated and
    may be removed in a future release.  (deprecated in 1.2.3) ...
