- oop - What is the definition of interface in object oriented . . .
An interface promises nothing about an action! The source of the confusion is that in most languages, if you have an interface type that defines a set of methods, the class that implements it "repeats" the same methods (but provides definition), so the interface looks like a skeleton or an outline of the class
- What is the difference between an interface and abstract class?
An interface is a good example of loose coupling (dynamic polymorphism dynamic binding) An interface implements polymorphism and abstraction It tells what to do but how to do is defined by the implementing class
- How can I define an interface for an array of objects?
Yes, your example of defining an interface only for the particular items would be a more useful way to do it It would be quite rare to have an array of items, but not want to conveniently reference a single item Using a real array also exposes length on the interface, which will probably be used quite often
- Interfaces vs Types in TypeScript - Stack Overflow
Hi, interface and type, looks similar but interfaces can use for "Declaration merging" and "Extends and implements" which "type" cannot do
- Interface defining a constructor signature? - Stack Overflow
An interface can indeed not be instantiated so doesn't need a constructor What I wanted to define was a signature to a constructor Exactly like an interface can define a signature of a certain method, the interface could define the signature of a constructor
- How do you declare an interface in C++? - Stack Overflow
How do I setup a class that represents an interface? Is this just an abstract base class?
- oop - How do I implement interfaces in python? - Stack Overflow
Implementing interfaces with abstract base classes is much simpler in modern Python 3 and they serve a purpose as an interface contract for plug-in extensions Create the interface abstract base class:
- How can I use interface as a C# generic type constraint?
That having been said, an interface constraint on T should allow reference comparisons between T and any other reference type, since reference comparisons are allowed between any interface and almost any other reference type, and allowing comparisons even that case would pose no problem
