| // Sometimes you want to give an action explicit template parameters |
| // that cannot be inferred from its value parameters. ACTION() and |
| // ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that |
| // and can be viewed as an extension to ACTION() and ACTION_P*(). |
| // |
| // The syntax: |
| // |
| // ACTION_TEMPLATE(ActionName, |
| // HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m), |
| // AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; } |
| // |
| // defines an action template that takes m explicit template |
| // parameters and n value parameters. name_i is the name of the i-th |
| // template parameter, and kind_i specifies whether it's a typename, |
| // an integral constant, or a template. p_i is the name of the i-th |
| // value parameter. |
| // |
| // Example: |
| // |
| // // DuplicateArg<k, T>(output) converts the k-th argument of the mock |
| // // function to type T and copies it to *output. |
| // ACTION_TEMPLATE(DuplicateArg, |
| // HAS_2_TEMPLATE_PARAMS(int, k, typename, T), |
| // AND_1_VALUE_PARAMS(output)) { |
| // *output = T(::std::get<k>(args)); |
| // } |
| // ... |
| // int n; |
| // EXPECT_CALL(mock, Foo(_, _)) |
| // .WillOnce(DuplicateArg<1, unsigned char>(&n)); |
| // |
| // To create an instance of an action template, write: |
| // |
| // ActionName<t1, ..., t_m>(v1, ..., v_n) |
| // |
| // where the ts are the template arguments and the vs are the value |
| // arguments. The value argument types are inferred by the compiler. |
| // If you want to explicitly specify the value argument types, you can |
| // provide additional template arguments: |
| // |
| // ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n) |
| // |
| // where u_i is the desired type of v_i. |
| // |
| // ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the |
| // number of value parameters, but not on the number of template |
| // parameters. Without the restriction, the meaning of the following |
| // is unclear: |
| // |
| // OverloadedAction<int, bool>(x); |
| // |
| // Are we using a single-template-parameter action where 'bool' refers |
| // to the type of x, or are we using a two-template-parameter action |
| // where the compiler is asked to infer the type of x? |
| // |
| // Implementation notes: |
| // |
| // GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and |
| // GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for |
| // implementing ACTION_TEMPLATE. The main trick we use is to create |
| // new macro invocations when expanding a macro. For example, we have |
| // |
| // #define ACTION_TEMPLATE(name, template_params, value_params) |
| // ... GMOCK_INTERNAL_DECL_##template_params ... |
| // |
| // which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...) |
| // to expand to |
| // |
| // ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ... |
| // |
| // Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the |
| // preprocessor will continue to expand it to |
| // |
| // ... typename T ... |
| // |
| // This technique conforms to the C++ standard and is portable. It |
| // allows us to implement action templates using O(N) code, where N is |
| // the maximum number of template/value parameters supported. Without |
| // using it, we'd have to devote O(N^2) amount of code to implement all |
| // combinations of m and n. |
| |
| // Declares the template parameters. |

| // InvokeArgument<1>(5, string("Hello"), std::ref(foo)) |

| // reference. |

| // 2. If the callable takes an argument by reference but std::ref() is |
| // not used, it will receive the reference to a copy of the value, |
| // instead of the original value. For example, when the 0-th |
| // argument of the mock function takes a const string&, the action |
| // |
| // InvokeArgument<0>(string("Hello")) |
| // |
| // makes a copy of the temporary string("Hello") object and passes a |
| // reference of the copy, instead of the original temporary object, |
| // to the callable. This makes it easy for a user to define an |
| // InvokeArgument action from temporary values and have it performed |
| // later. |
