object-oriented-extension

Provides support for "protected" fields and methods without conventions. Also provides inherit functionality.

Usage

if (global.objectOrientedExtension) {
    require("object-oriented-extension/ObjectOriented/JsExtension");
    // or simply: 'global.include("ObjectOriented/JsExtension");', when using include-js package
}
var SomeClass = function (protectedData/*, some other arguments for constructor) {
    protectedData.protectedField = 'some value';
    protectedData.protectedMethod = function () {};
    // Realization
};
SomeClass = SomeClass.injectProtected(); // <- that's it
var SomeChildClass = function (protectedData/*, ... */) {
    SomeClass.call(this, someArgument); // <- Call parent constructor
    // Realization
    this.someMethod = function (someArg) {
        SomeClass.someMethod.call(this, someArg); // <- Call parent method
    };
};
SomeChildClass = SomeChildClass.extend(SomeClass); // <- simply like this (call of "injectProtected" is fully optional in that case)

Almost useless bonus:

// In definition of some class...
this.someMethod = Function.abstractMethod();
this.someAnotherMethod = (function () {}).makeAbstract();
