Decorators¶
flutils offers the following decorators:
-
@
cached_property
[source]¶ A property decorator that is only computed once per instance and then replaces itself with an ordinary attribute.
Deleting the attribute resets the property.
Note
In Python 3.8 the
functools.cached_property
decorator was added. It is recommended to use the built-infunctools.cached_property
; provided you’re using Python >= 3.8.cached_property
remains for use with Python 3.6 and 3.7.Example
Code:
from flutils.decorators import cached_property class MyClass: def __init__(self): self.x = 5 @cached_property def y(self): return self.x + 1
Usage:
>>> obj = MyClass() >>> obj.y 6
New in version 0.2.0
