py-object-factory
objectfactory is a python package to easily implement the factory design pattern for object creation, serialization, and polymorphism
- designed to support polymorphism
- integrates seamlessly with marshmallow and other serialization frameworks
- schema inherent in class definition
- load any object with a generic interface
- serialize objects to JSON
Example
Simple shapes example:
import objectfactory
@objectfactory.register
class Square( objectfactory.Serializable ):
side = objectfactory.Field()
def get_area( self ):
return self.side * self.side
@objectfactory.register
class Triangle( objectfactory.Serializable ):
base = objectfactory.Field()
height = objectfactory.Field()
def get_area( self ):
return 0.5 * self.base * self.height
serialized_data = [
{"_type": "Square", "side": 2.0},
{"_type": "Triangle", "base": 1.75, "height": 2.50},
{"_type": "Square", "side": 1.5},
]
for data in serialized_data:
shape = objectfactory.create( data )
print( 'class type: {}, shape area: {}'.format( type( shape ), shape.get_area() ) )
Output:
class type: <class '__main__.Square'>, shape area: 4.0
class type: <class '__main__.Triangle'>, shape area: 2.1875
class type: <class '__main__.Square'>, shape area: 2.25
