deprecated¶

astropy.utils.decorators.deprecated(since, message='', name='', alternative='', pending=False, obj_type=None, warning_type=<class 'astropy.utils.exceptions.AstropyDeprecationWarning'>)[source]

Used to mark a function or class as deprecated.

To mark an attribute as deprecated, use deprecated_attribute.

Parameters
sincestr

The release at which this API became deprecated. This is required.

messagestr, optional

Override the default deprecation message. The format specifier func may be used for the name of the function, and alternative may be used in the deprecation message to insert the name of an alternative to the deprecated function. obj_type may be used to insert a friendly name for the type of object being deprecated.

namestr, optional

The name of the deprecated function or class; if not provided the name is automatically determined from the passed in function or class, though this is useful in the case of renamed functions, where the new function is just assigned to the name of the deprecated function. For example:

def new_function():
...
oldFunction = new_function

alternativestr, optional

An alternative function or class name that the user may use in place of the deprecated object. The deprecation warning will tell the user about this alternative if provided.

pendingbool, optional

If True, uses a AstropyPendingDeprecationWarning instead of a warning_type.

obj_typestr, optional

The type of this object, if the automatically determined one needs to be overridden.

warning_typewarning

Warning to be issued. Default is AstropyDeprecationWarning.
