Here's a better version, show the chaining of dependencies.
#!/usr/bin/rhino
var Registry = {
factories : {},
instances : {},
register: function(name,factory){
this.factories[name] = factory;
this.__defineGetter__(name, function() {
if (!this.instances[name]){
this.instances[name] = this.factories[name]();
}
return this.instances[name];
});
}
}
Registry.register("teststring",function(){
return "Injected";
});
Registry.register("testobj",function(){
var that = {};
that.string = Registry.teststring;
that.execute = function(){
print(that.string);
}
return that;
});
Registry.testobj.execute();
