objectory 0.0.8

A light library for general purpose object factories

objectory = object + factory

Overview

A Python library for general purpose object factories. In particular, it focuses on dynamic object factory implementations where objects can be registered dynamically without changing the code of the factory. An object factory can be used to instantiate an object from its configuration. The current implementation contains both abstract factory and registry approaches.

factory

>>> from objectory import factory
>>> class MyClass:
...     pass
...
>>> obj = factory("MyClass")
>>> print(obj)
<__main__.MyClass object at 0x123456789>

abstract factory

>>> from objectory import AbstractFactory
>>> class BaseClass(metaclass=AbstractFactory):
...     pass
...
>>> class MyClass(BaseClass):
...     pass
...
>>> obj = BaseClass.factory("MyClass")
>>> print(obj)
<__main__.MyClass object at 0x123456789>

registry

>>> from objectory import Registry
>>> registry = Registry()
>>> @registry.register()
... class MyClass:
...     pass
...
>>> obj = registry.factory("MyClass")
>>> print(obj)
<__main__.MyClass object at 0x123456789>

API stability

:warning: While objectory is in development stage, no API is guaranteed to be stable from one release to the next. In fact, it is very likely that the API will change multiple times before a stable 1.0.0 release. In practice, this means that upgrading objectory to a new version will possibly break any code that was using the old version of objectory.
