Decorators

flutils offers the following decorators:

flutils.cached_property(func)

A property decorator that is only computed once per instance and then replaces itself with an ordinary attribute.

Deleting the attribute resets the property.

Example

Code:

from flutils 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
>>> obj.y
6
