Methods

Methods

Methods are functions whose first argument is named this and is a pointer to a struct type.

func myMethod(this *MyStruct) {

}

Calling Methods

Methods can be called using method calls

subject_value.myMethod(argument1, argument2, argumentN)

Struct/Class Domains

When functions are declared inside of struct domains, they are automatically turned into methods and gain an implicit this parameter.

struct Person (firstname, lastname String) {
    func greet {
        printf("Hello, my name is %S %S.\n", this.firstname, this.lastname)
    }
}

which is equivalent to

struct Person (firstname, lastname String)

func greet(this *Person) {
    printf("Hello, my name is %S %S.\n", this.firstname, this.lastname)
}

See structures for more information.

Virtual Methods

Virtual methods are methods which are dispatched at runtime. They can be defined on classes. See classes for more information.

import basics

class Shape () {
    constructor {}

    virtual func getArea() float = 0.0
}

class Rectangle extends Shape (w, h float) {
    constructor(w, h float){
        this.w = w
        this.h = h
    }

    override func getArea() float = this.w * this.h
}

func main {
    shape *Shape = new Rectangle(5.0f, 10.0f)
    defer delete shape
    print(shape.getArea())
}
