-// |
-// A smart pointer class for reference counted objects. Use this class instead |
-// of calling AddRef and Release manually on a reference counted object to |
-// avoid common memory leaks caused by forgetting to Release an object |
-// reference. Sample usage: |
-// |
-// class MyFoo : public RefCounted<MyFoo> { |
-// ... |
-// }; |
-// |
-// void some_function() { |
-// scoped_refptr<MyFoo> foo = new MyFoo(); |
-// foo->Method(param); |
-// // |foo| is released when this function returns |
-// } |
-// |
-// void some_other_function() { |
-// scoped_refptr<MyFoo> foo = new MyFoo(); |
-// ... |
-// foo = NULL; // explicitly releases |foo| |
-// ... |
-// if (foo) |
-// foo->Method(param); |
-// } |
-// |
-// The above examples show how scoped_refptr<T> acts like a pointer to T. |
-// Given two scoped_refptr<T> classes, it is also possible to exchange |
-// references between the two objects, like so: |
-// |
-// { |
-// scoped_refptr<MyFoo> a = new MyFoo(); |
-// scoped_refptr<MyFoo> b; |
-// |
-// b.swap(a); |
-// // now, |b| references the MyFoo object, and |a| references NULL. |
-// } |
-// |
-// To make both |a| and |b| in the above example reference the same MyFoo |
-// object, simply use the assignment operator: |
-// |
-// { |
-// scoped_refptr<MyFoo> a = new MyFoo(); |
-// scoped_refptr<MyFoo> b; |
-// |
-// b = a; |
-// // now, |a| and |b| each own a reference to the same MyFoo object. |
-// } |
-// |
