51 // Sometimes you want to give an action explicit template parameters
52 // that cannot be inferred from its value parameters. ACTION() and
53 // ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
54 // and can be viewed as an extension to ACTION() and ACTION_P*().
55 //
56 // The syntax:
57 //
58 // ACTION_TEMPLATE(ActionName,
59 // HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
60 // AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
61 //
62 // defines an action template that takes m explicit template
63 // parameters and n value parameters. name_i is the name of the i-th
64 // template parameter, and kind_i specifies whether it's a typename,
65 // an integral constant, or a template. p_i is the name of the i-th
66 // value parameter.
67 //
68 // Example:
69 //
70 // // DuplicateArg<k, T>(output) converts the k-th argument of the mock
71 // // function to type T and copies it to *output.
72 // ACTION_TEMPLATE(DuplicateArg,
73 // HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
74 // AND_1_VALUE_PARAMS(output)) {
75 // *output = T(::std::get<k>(args));
76 // }
77 // ...
78 // int n;
79 // EXPECT_CALL(mock, Foo(_, _))
80 // .WillOnce(DuplicateArg<1, unsigned char>(&n));
81 //
82 // To create an instance of an action template, write:
83 //
84 // ActionName<t1, ..., t_m>(v1, ..., v_n)
85 //
86 // where the ts are the template arguments and the vs are the value
87 // arguments. The value argument types are inferred by the compiler.
88 // If you want to explicitly specify the value argument types, you can
89 // provide additional template arguments:
90 //
91 // ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
92 //
93 // where u_i is the desired type of v_i.
94 //
95 // ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
96 // number of value parameters, but not on the number of template
97 // parameters. Without the restriction, the meaning of the following
98 // is unclear:
99 //
100 // OverloadedAction<int, bool>(x);
101 //
102 // Are we using a single-template-parameter action where 'bool' refers
103 // to the type of x, or are we using a two-template-parameter action
104 // where the compiler is asked to infer the type of x?
105 //
106 // Implementation notes:
107 //
108 // GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
109 // GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
110 // implementing ACTION_TEMPLATE. The main trick we use is to create
111 // new macro invocations when expanding a macro. For example, we have
112 //
113 // #define ACTION_TEMPLATE(name, template_params, value_params)
114 // ... GMOCK_INTERNAL_DECL_##template_params ...
115 //
116 // which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
117 // to expand to
118 //
119 // ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
120 //
121 // Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
122 // preprocessor will continue to expand it to
123 //
124 // ... typename T ...
125 //
126 // This technique conforms to the C++ standard and is portable. It
127 // allows us to implement action templates using O(N) code, where N is
128 // the maximum number of template/value parameters supported. Without
129 // using it, we'd have to devote O(N^2) amount of code to implement all
130 // combinations of m and n.
131 
132 // Declares the template parameters.

483 // The InvokeArgument<N>(a1, a2, ..., a_k) action invokes the N-th
484 // (0-based) argument, which must be a k-ary callable, of the mock
485 // function, with arguments a1, a2, ..., a_k.
486 //
487 // Notes:
488 //
489 // 1. The arguments are passed by value by default. If you need to
490 // pass an argument by reference, wrap it inside ByRef(). For
491 // example,
492 //
493 // InvokeArgument<1>(5, string("Hello"), ByRef(foo))
494 //
495 // passes 5 and string("Hello") by value, and passes foo by
496 // reference.
497 //
498 // 2. If the callable takes an argument by reference but ByRef() is
499 // not used, it will receive the reference to a copy of the value,
500 // instead of the original value. For example, when the 0-th
501 // argument of the mock function takes a const string&, the action
502 //
503 // InvokeArgument<0>(string("Hello"))
504 //
505 // makes a copy of the temporary string("Hello") object and passes a
506 // reference of the copy, instead of the original temporary object,
507 // to the callable. This makes it easy for a user to define an
508 // InvokeArgument action from temporary values and have it performed
509 // later.
