-// A MockFunction<F> class has one mock method whose type is F. It is
-// useful when you just want your test code to emit some messages and
-// have Google Mock verify the right messages are sent (and perhaps at
-// the right times). For example, if you are exercising code:
-//
-// Foo(1);
-// Foo(2);
-// Foo(3);
-//
-// and want to verify that Foo(1) and Foo(3) both invoke
-// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
-//
-// TEST(FooTest, InvokesBarCorrectly) {
-// MyMock mock;
-// MockFunction<void(string check_point_name)> check;
-// {
-// InSequence s;
-//
-// EXPECT_CALL(mock, Bar("a"));
-// EXPECT_CALL(check, Call("1"));
-// EXPECT_CALL(check, Call("2"));
-// EXPECT_CALL(mock, Bar("a"));
-// }
-// Foo(1);
-// check.Call("1");
-// Foo(2);
-// check.Call("2");
-// Foo(3);
-// }
-//
-// The expectation spec says that the first Bar("a") must happen
-// before check point "1", the second Bar("a") must happen after check
-// point "2", and nothing should happen between the two check
-// points. The explicit check points make it easy to tell which
-// Bar("a") is called by which call to Foo().
-//
-// MockFunction<F> can also be used to exercise code that accepts
-// std::function<F> callbacks. To do so, use AsStdFunction() method
-// to create std::function proxy forwarding to original object's Call.
-// Example:
-//
-// TEST(FooTest, RunsCallbackWithBarArgument) {
-// MockFunction<int(string)> callback;
-// EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
-// Foo(callback.AsStdFunction());
-// }
