Deprecator

class nibabel.deprecator.Deprecator(version_comparator, warn_class=<type 'exceptions.DeprecationWarning'>, error_class=<class 'nibabel.deprecator.ExpiredDeprecationError'>)

Bases: object

Class to make decorator marking function or method as deprecated

The decorated function / method will:

• Raise the given warning_class warning when the function / method gets called, up to (and including) version until (if specified);
• Raise the given error_class error when the function / method gets called, when the package version is greater than version until (if specified).

Parameters:

version_comparator : callable

Callable accepting string as argument, and return 1 if string represents a higher version than encoded in the version_comparator, 0 if the version is equal, and -1 if the version is lower. For example, the version_comparator may compare the input version string to the current package version string.

warn_class : class, optional

Class of warning to generate for deprecation.

error_class : class, optional

Class of error to generate when version_comparator returns 1 for a given argument of until in the __call__ method (see below).

Parameters:
