  • I mostly come to prefer composition, this approach apparently even has a wiki page. But that’s in part because I use Rust that forbids inheritance, and don’t have such bullshit (from delegation wiki page):

    class A {
        void foo() {
            // "this" also known under the names "current", "me" and "self" in other languages
            this.bar();
        }
    
        void bar() {
            print("a.bar");
        }
    }
    
    class B {
        private delegate A a; // delegation link
    
        public B(A a) {
            this.a = a;
        }
    
        void foo() {
            a.foo(); // call foo() on the a-instance
        }
    
        void bar() {
            print("b.bar");
        }
    }
    
    a = new A();
    b = new B(a); // establish delegation between two objects
    

    Calling b.foo() will result in b.bar being printed, since this refers to the original receiver object, b, within the context of a. The resulting ambiguity of this is referred to as object schizophrenia

    Translating the implicit this into an explicit parameter, the call (in B, with a a delegate) a.foo() translates to A.foo(b), using the type of a for method resolution, but the delegating object b for the this argument.

    Why would one substitute b as this when called from b.a is beyond me, seriously.










  • you can just say Americans people, everyone will know who you’re talking about USA.

    Fixed this for you. Kind of a pet peeve of mine when people use ‘defaults’, like everyone on the internet are in America, or if you’re talking to someone from a capital of a different country they will assume you’re also in the capital, everyone lives in America timezone, everyone using English uses en_US locale, and if by some bizarre chance you’re in another country you can only switch language and country together, etc
