hbutils.design

Design pattern utilities for the hbutils.design package.

This package provides lightweight, Pythonic implementations of several classic design patterns. It acts as a convenience entry point that re-exports all public APIs from its submodules, allowing consumers to import from hbutils.design directly.

The package includes the following public components:

FinalMeta - Metaclass that prevents class inheritance (final class)
SingletonMeta - Metaclass implementing the singleton pattern
Decorator helpers from hbutils.design.decorator
Observer pattern utilities from hbutils.design.observer

Note

This module is an aggregation layer that imports and exposes public objects from its submodules. Refer to each submodule for detailed behavior and API specifics.

Example:

>>> from hbutils.design import SingletonMeta
>>> class MyClass(metaclass=SingletonMeta):
...     pass
>>> instance1 = MyClass()
>>> instance2 = MyClass()
>>> instance1 is instance2
True
