haxe interface

In Haxe, an interface is a collection of related methods that a class can implement. An interface defines a set of method signatures, but does not provide any implementation for those methods. A class that implements an interface must provide an implementation for all the methods defined in the interface.

Here's an example of how you can define and use an interface in Haxe:

// define an interface
interface Shape {
    function area():Float;
}

// define a class that implements the Shape interface
class Circle implements Shape {
    var radius:Float;

    public function new(radius:Float) {
        this.radius = radius;
    }

    public function area():Float {
        return Math.PI * radius * radius;
    }
}

// create an instance of the Circle class
var circle = new Circle(2.0);

// call the area method on the circle object
trace(circle.area()); // prints 12.566370614359172

This code defines an interface called Shape with a single method called area(). It then defines a class called Circle that implements the Shape interface and provides an implementation for the area() method. The Circle class has a field called radius and a constructor that initializes the field. The area() method calculates and returns the area of the circle based on the radius.

Finally, the code creates an instance of the Circle class and calls the area() method on it, printing the result to the console.

Interfaces are a useful way to define a common set of methods that different classes can implement in different ways. They can also be used to specify the type of an object in a type-safe way, as you can use an interface as the type of a variable or a parameter.

For more information about interfaces and other features of the Haxe programming language, you can refer to the Haxe documentation (https://haxe.org/documentation/).
