What do I need to do to see that the protected is active, need a separate module?

// Source: https://tour.dlang.org/tour/en/basics/classes
class Any
{
    // protected is just seen by inheriting
    // classes
    protected string type;

    this(string type) {
        this.type = type;
    }

    // public is implicit by the way
    string getType() {
        return type;
    }
}

import std.stdio, std.string;
import std.uni : isWhite;

void main()
{
    Any any = new Any("bu bir deneme");
        any.getType.writeln("--> Split:");
        any.type.split!isWhite.writeln;
        any.type = "deneme";
        any.type.writeln;
}/* Console Out:
bu bir deneme--> Split:
["bu", "bir", "deneme"]
deneme
*/

Addition made for one of the inherited class:

override string convertToString() {
        import std.conv : to;
        // The swiss army knife of conversion.
        this.type = "int";
        return to!string(type);
    }

The type is not there but it is changed without super! Why?

Thanks...

Okay, what about the 2nd question (super or this).

import app, std.stdio;
void main()
{
  auto any = new Any("int");
  //any.get().writeln; /*
  assert(any.data == "int"); /* main.d(7): Error:
           no property `data` for type `app.Any`,
           did you mean `app.Any.data`? */

}

module app;

class Any
{
    protected string data;

    this(string data) { this.data = data;
    }

    @property get() { return data; }
}

string getData(Any test) { return test.Data; }

What is the difference between protected and private? Also how can a function outside of the class access it?

private in D means "this symbol can only be accessed from the module where it's defined."

protected in D means "this symbol can only be accessed from (a) the module where it's defined, and (b) classes that inherit from the class where it's defined."
