与另一个模板的模板专业化

Question

假设我有两个模板类

template < class T >
class Foo
{
    /**/
};

和

template < class T >
class Bar
{
     /**/
};

如何将Foo与Bar<T>进行专门化？ 什么是语法？ 是吗

template<>
template<class T>
class Foo<Bar<T>>
{ /**/ };

或

template<class T>
class Foo<Bar<T>>
{ /**/ };

或任何其他语法??

语法是最后一个：

myapp.controller("DailyController", function($scope) {
  $scope.GetDataAndDrawChart = function(data) {
    // CommmonApi is my service which is fetching data from database.
    $scope.pieData = [{
      name: "Microsoft Internet Explorer",
      y: 56.33
    }, {
      name: "Chrome",
      y: 24.03,
      sliced: true,
      selected: true
    }, {
      name: "Firefox",
      y: 10.38
    }, {
      name: "Safari",
      y: 4.77
    }, {
      name: "Opera",
      y: 0.91
    }, {
      name: "Proprietary or Undetectable",
      y: 0.2
    }]  

  }
});
