+
+// The intention of this file is to make possible using GMock actions in
+// all of its syntactic beauty. Classes and helper functions can be used as
+// more generic variants of Task and Callback classes (see base/task.h)
+// Mutant supports both pre-bound arguments (like Task) and call-time
+// arguments (like Callback) - hence the name. :-)
+//
+// DispatchToMethod supports two sets of arguments: pre-bound (P) and
+// call-time (C). The arguments as well as the return type are templatized.
+// DispatchToMethod will also try to call the selected method even if provided
+// pre-bound arguments does not match exactly with the function signature
+// hence the X1, X2 ... XN parameters in CreateFunctor.
+//
+// Additionally you can bind the object at calltime by binding a pointer to
+// pointer to the object at creation time - before including this file you
+// have to #define GMOCK_MUTANT_INCLUDE_LATE_OBJECT_BINDING.
+//
+// TODO(stoyan): It's yet not clear to me should we use T& and T&* instead
+// of T* and T** when we invoke CreateFunctor to match the EXPECT_CALL style.
+//
+//
+// Sample usage with gMock:
+//
+// struct Mock : public ObjectDelegate {
+//   MOCK_METHOD2(string, OnRequest(int n, const string& request));
+//   MOCK_METHOD1(void, OnQuit(int exit_code));
+//   MOCK_METHOD2(void, LogMessage(int level, const string& message));
+//
+//   string HandleFlowers(const string& reply, int n, const string& request) {
+//     string result = SStringPrintf("In request of %d %s ", n, request);
+//     for (int i = 0; i < n; ++i) result.append(reply)
+//     return result;
+//   }
+//
+//   void DoLogMessage(int level, const string& message) {
+//   }
+//
+//   void QuitMessageLoop(int seconds) {
+//     MessageLoop* loop = MessageLoop::current();
+//     loop->PostDelayedTask(FROM_HERE, new MessageLoop::QuitTask,
+//                           1000 * seconds);
+//   }
+// };
+//
+// Mock mock;
+// // Will invoke mock.HandleFlowers("orchids", n, request)
+// // "orchids" is a pre-bound argument, and <n> and <request> are call-time
+// // arguments - they are not known until the OnRequest mock is invoked.
+// EXPECT_CALL(mock, OnRequest(Ge(5), StartsWith("flower"))
+//   .Times(1)
+//   .WillOnce(Invoke(CreateFunctor(&mock, &Mock::HandleFlowers,
+//       string("orchids"))));
+//
+//
+// // No pre-bound arguments, two call-time arguments passed
+// // directly to DoLogMessage
+// EXPECT_CALL(mock, OnLogMessage(_, _))
+//   .Times(AnyNumber())
+//   .WillAlways(Invoke(CreateFunctor, &mock, &Mock::DoLogMessage));
+//
+//
+// // In this case we have a single pre-bound argument - 3. We ignore
+// // all of the arguments of OnQuit.
+// EXCEPT_CALL(mock, OnQuit(_))
+//   .Times(1)
+//   .WillOnce(InvokeWithoutArgs(CreateFunctor(
+//       &mock, &Mock::QuitMessageLoop, 3)));
+//
+// MessageLoop loop;
+// loop.Run();
+//
+//
+//  // Here is another example of how we can set an action that invokes
+//  // method of an object that is not yet created.

+//   MOCK_METHOD1(void, DemiurgeCreated(Demiurge*));
