To mark a method, function, or class as being deprecated do this:: from incremental import Version from twisted.python.deprecate import deprecated @deprecated(Version("Twisted", 22, 10, 0)) def badAPI(self, first, second): ''' Docstring for badAPI. ''' ... @deprecated(Version("Twisted", 22, 10, 0)) class BadClass: ''' Docstring for BadClass. ''' The newly-decorated badAPI will issue a warning when called, and BadClass will issue a warning when instantiated. Both will also have a deprecation notice appended to their docstring. To deprecate properties you can use:: from incremental import Version from twisted.python.deprecate import deprecatedProperty class OtherwiseUndeprecatedClass: @deprecatedProperty(Version("Twisted", 22, 10, 0)) def badProperty(self): ''' Docstring for badProperty. ''' @badProperty.setter def badProperty(self, value): ''' Setter sill also raise the deprecation warning. ''' To mark module-level attributes as being deprecated you can use:: badAttribute = "someValue" ... deprecatedModuleAttribute( Version("Twisted", 22, 10, 0), "Use goodAttribute instead.", "your.full.module.name", "badAttribute") The deprecated attributes will issue a warning whenever they are accessed. If the attributes being deprecated are in the same module as the L{deprecatedModuleAttribute} call is being made from, the C{__name__} global can be used as the C{moduleName} parameter. To mark an optional, keyword parameter of a function or method as deprecated without deprecating the function itself, you can use:: @deprecatedKeywordParameter(Version("Twisted", 22, 10, 0), "baz") def someFunction(foo, bar=0, baz=None): ...
