// Inject a service into a controller (source: http://stackoverflow.com/a/14418384/477697)

function MyCtrl($scope, $injector) {
  $scope.doSomething = function(someService) {
    var service = $injector.get(someService)  // someService contains the name of a service
    service.value += 10
}

// Define a service (source: http://stackoverflow.com/a/15904939/477697)

function MyObjectWithParam($rootScope, name) {
  this.$rootScope = $rootScope;
  this.name = name;
}
MyObjectWithParam.prototype.getText = function () {
  return this.name;
};

App.factory('MyObjectWithParam', function ($injector) {
  return function(name) { 
    return $injector.instantiate(MyObjectWithParam,{ name: name });
  };
});

// Prototypal inheritance with controllers (source: http://blog.mgechev.com/2013/12/18/inheritance-services-controllers-in-angularjs/)

function BaseCtrl($scope, $location, ...) {
  $scope.commonScopeMethod = function () {
    //body
  };
  $scope.commonVar = 42;
}
BaseCtrl.prototype.commonMethod1 = function () {
  //body
};
BaseCtrl.prototype.commonMethod2 = function () {
  //body
};

function ChildCtrl1($scope, $location, ...) {
  BaseCtrl.call(this, $scope, $location, ...);
  $scope.childScopeMethod = function () {
  };
}
 
ChildCtrl1.prototype = Object.create(BaseCtrl.prototype);
 
ChildCtrl1.prototype.childMethod1 = function () {
  this.commonMethod1();
};
 
myModule.controller('ChildCtrl1', ChildCtrl1);
