The following cache types are available: - ``time_cache`` can be used to cache something for just a limited time span, which can be useful if there's user interaction and the user cannot react faster than a certain time. This module is one of the reasons why |jedi| is not thread-safe. As you can see there are global variables, which are holding the cache information. Some of these variables are being cleaned after every API usage. éN)Úwraps)Úsettings)Ú parser_cachecsdˆj‰‡‡fdd„}|S)an Decorator for methods:: class A(object): def x(self): if self._x: self._x = 10 return self._x Becomes:: class A(object): @underscore_memoization def x(self): return 10 A now has an attribute ``_x`` written by this decorator.
