Introduction¶
Python library unicum¶
unicum consists of multiple object implementations that implement various factory pattern. All types merge into on type VisibleObject and each type contributes bits and piece.
The visible obj focus on robust and simple construction from a dictionary via PersistentObject having values only simple types or containers containers of simple types.
These values are translated via FatoryObject into more complex structures which are take from a factory.
Or, alternatively, using DataRange into something similar to a data_frame type in R, a table with column and row names as well as common types for each column values.
Inheriting from LinkedObject provides functionality to swap or update attributes at runtime
Example Usage¶
Using FactoryObject:
>>> from unicum import FactoryObject
>>> class Currency(FactoryObject): __factory = dict()
>>> class EUR(Currency): pass
>>> class USD(Currency): pass
>>> EUR().register() # registers USD() instance with class name 'EUR'
>>> eur = Currency('EUR') # picks instance with key 'EUR' from currency cache
>>> eur == EUR() # picks instance with key given by class name 'EUR' from currency cache, too.
True
>>> eur2 = eur.__class__('EUR') # picks instance with key 'EUR' from currency cache
>>> eur == eur2
True
>>> usd = USD().register() # registers USD() instance with class name 'USD'
>>> usd.register('usd') # registers usd with name 'usd'
>>> usd == USD()
True
>>> eur == eur.__class__('USD')
False
>>> usd == eur.__class__('USD')
True
>>> usd == Currency('usd')
True
Using LinkedObject:
>>> from unicum import LinkedObject
