ClassRegistry
At the intersection of the Registry and Factory patterns lies the ClassRegistry:
Define global factories that generate new class instances based on configurable keys.
Seamlessly create powerful service registries.
Integrate with setuptools’s entry_points system to make your registries infinitely extensible by 3rd-party libraries!
And more!
Getting Started
Create a registry using the class_registry.ClassRegistry class, then decorate any classes that you wish to register with its register method:
from class_registry import ClassRegistry
pokedex = ClassRegistry()
@pokedex.register('fire')
class Charizard(Pokemon):
...
@pokedex.register('grass')
class Bulbasaur(Pokemon):
...
@pokedex.register('water')
class Squirtle(Pokemon):
...To create a class instance from a registry, use the subscript operator:
# Charizard, I choose you!
fighter1 = pokedex['fire']
# CHARIZARD fainted!
# How come my rival always picks the type that my pokémon is weak against??
fighter2 = pokedex['grass']Advanced Usage
There’s a whole lot more you can do with ClassRegistry, including:
Provide args and kwargs to new class instances.
Automatically register non-abstract classes.
Integrate with setuptools’s entry_points system so that 3rd-party libraries can add their own classes to your registries.
Wrap your registry in an instance cache to create a service registry.
And more!
For more advanced usage, check out the documentation on RTD!
