- // 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.
