How To Make An Object’S Clones Follow The Same Function [Closed] Update Mới

To make an object’s clones follow the same function, you can use object-oriented programming techniques such as inheritance or delegation.

Inheritance involves creating a base class that defines the common properties and functions of the object and then creating subclasses that inherit those properties and functions. The subclasses can then add or modify properties and functions as needed. When you create a clone of the object, it will inherit the same properties and functions as the original object.

Delegation involves creating a separate object that handles the common properties and functions of the object, and then creating clones of that object that delegate to it for those properties and functions. When you create a clone of the object, it will delegate to the same object as the original object.

For example, in Python, you can use the copy module to create clones of an object, and then use inheritance or delegation to ensure that the clones follow the same function:

python
import copy

class Base:
    def __init__(self, x):
        self.x = x
    
    def func(self):
        print(self.x)

class Subclass(Base):
    def __init__(self, x, y):
        super().__init__(x)
        self.y = y
    
    def func(self):
        super().func()
        print(self.y)

class Delegator:
    def __init__(self, base):
        self.base = base
    
    def func(self):
        self.base.func()

base = Base(1)
sub = Subclass(2, 3)
delegator = Delegator(base)

clones = [copy.deepcopy(base), copy.deepcopy(sub), Delegator(copy.deepcopy(base))]
for clone in clones:
    clone.func() # prints 1, 1 3, 1

In this example, Base defines a common property x and a function func that prints x. Subclass inherits from Base and adds a property y and a modified function func that calls Base.func and then prints y. Delegator takes a Base object as an argument and delegates its func function to it.

Then, clones of Base, Subclass, and a Delegator object that delegates to a clone of Base are created using the copy.deepcopy function. Each clone’s func function is called, and they all print the same values, demonstrating that they all follow the same function.
