Currently unmaintained since I have moved from Microfocus Service Manager to ServiceNow - Sorry guys!
This class extending engine is a fork from https://github.com/ironboy/classier.
It includes only the required changes to make it work inside the service manager.
A detailed description how this engine works is available here: https://classier.cloudeducation.se/
-
You have to define the
_classvariable, because the service manager has no DOM or something else which is required to use the existing functionality from the classier engine -
The definition of private and protected variables has no effect. It's always possible to access private & protected variables - The reason for this is the old javascript version.
var classier = system.library.classier.getClass();
var Animal = classier.$extend({
_class : "Animal",
__init__ : function(name, age) {
this.name = name;
this.age = age;
},
health: 100,
_secret: "I'm always hungry.",
__extraSecret: "I'm scared of humans.",
// as well as methods
die : function() {
this.health = 0;
},
eat : function(what) {
this.health += 5;
},
tellSecret : function() {
return this._secret;
},
tellExtraSecret : function() {
return this.__extraSecret;
}
});
var Tiger = Animal.$extend({
_class : "Tiger",
eat : function(animal) {
this.$super(animal);
animal.die();
