    _defineProperties: function () {
        this._super();
 
        /**

var WithEncryption = {
    encrypt: function () {
        console.log('encrypted!');
    }
}
 
/**
 * @class ClassWithEncryption
 * @mixes WithEncryption
 */
var ClassWithEncryption = ClassX.mix(WithEncryption).extend({
    /**
     * @constructor
     * @protected
     */
    _initialize: function() {
        this._super();
 
        this.encrypt();
    }
});
 
var instance = new ClassWithEncryption(); // encrypted!
