Interface Decorator

allows the use of the @Interface class decorator, which allows for partial interface behavior currently only preventing direct instantiation. future features hope to include method detection and force children implementations, however, this can be accomplished with the ABC package.

this package is designed to be light weight and extremely simple to use. one @ to rule them all. in this case, enforcing typical interface behaviors with good readability.

install windows

pip install InterfaceTools

Mac

pip3 install InterfaceTools

Instructions:

above any classes you wish to become an interface and restrict instantaition to only children:

from Leviathan.interface import Interface

@interface
class MyClass():

    def __init__(self, *args,**kwargs):
       pass 

    def Method():pass

that is all there is to it. this decorator then restricts this class never to instantiate on its own; meaning the following:

foo = MyClass()

which gives the following error:

InterfaceInstancingError: The class MyClass is an interface. Interfaces cannot be instantiated.

each interface requires the follwoing init function to allow for parameters, it can stay empty.

   def __init__(self, *args,**kwargs):
       pass

Additionally, unlike interfaces in C# or Java, you are not required to implement their methods. however, if you desire that functionality you can use this with the ABC package to enforce children-overriding methods

example:

from abc import ABCMeta, abstractmethod

@Interface 
class myClass(metaclass=ABCMeta):
    
    def __init__(self, *args,**kwargs):
       pass 
    
    @abstractmethod
    def method():pass

the example above will give you a full C# or Java-like interface.

other things you can do with this module are interface inheritance:

example:

@Interface 
class myClass():
    pass
@Interface
class class2(myClass):
    pass

which you can also inherit from regular classes as well.

class myClass():
    pass
@Interface
class class2(myClass):
    pass

the interface wrapper is fully compatible with all the default Python functions, and the ABC package for further control over your interface.
