  53 // Sometimes you want to give an action explicit template parameters
  54 // that cannot be inferred from its value parameters.  ACTION() and
  55 // ACTION_P*() don't support that.  ACTION_TEMPLATE() remedies that
  56 // and can be viewed as an extension to ACTION() and ACTION_P*().
  57 //
  58 // The syntax:
  59 //
  60 //   ACTION_TEMPLATE(ActionName,
  61 //                   HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
  62 //                   AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
  63 //
  64 // defines an action template that takes m explicit template
  65 // parameters and n value parameters.  name_i is the name of the i-th
  66 // template parameter, and kind_i specifies whether it's a typename,
  67 // an integral constant, or a template.  p_i is the name of the i-th
  68 // value parameter.
  69 //
  70 // Example:
  71 //
  72 //   // DuplicateArg<k, T>(output) converts the k-th argument of the mock
  73 //   // function to type T and copies it to *output.
  74 //   ACTION_TEMPLATE(DuplicateArg,
  75 //                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
  76 //                   AND_1_VALUE_PARAMS(output)) {
  77 //     *output = T(::std::get<k>(args));
  78 //   }
  79 //   ...
  80 //     int n;
  81 //     EXPECT_CALL(mock, Foo(_, _))
  82 //         .WillOnce(DuplicateArg<1, unsigned char>(&n));
  83 //
  84 // To create an instance of an action template, write:
  85 //
  86 //   ActionName<t1, ..., t_m>(v1, ..., v_n)
  87 //
  88 // where the ts are the template arguments and the vs are the value
  89 // arguments.  The value argument types are inferred by the compiler.
  90 // If you want to explicitly specify the value argument types, you can
  91 // provide additional template arguments:
  92 //
  93 //   ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
  94 //
  95 // where u_i is the desired type of v_i.
  96 //
  97 // ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
  98 // number of value parameters, but not on the number of template
  99 // parameters.  Without the restriction, the meaning of the following
 100 // is unclear:
 101 //
 102 //   OverloadedAction<int, bool>(x);
 103 //
 104 // Are we using a single-template-parameter action where 'bool' refers
 105 // to the type of x, or are we using a two-template-parameter action
 106 // where the compiler is asked to infer the type of x?
 107 //
 108 // Implementation notes:
 109 //
 110 // GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
 111 // GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
 112 // implementing ACTION_TEMPLATE.  The main trick we use is to create
 113 // new macro invocations when expanding a macro.  For example, we have
 114 //
 115 //   #define ACTION_TEMPLATE(name, template_params, value_params)
 116 //       ... GMOCK_INTERNAL_DECL_##template_params ...
 117 //
 118 // which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
 119 // to expand to
 120 //
 121 //       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
 122 //
 123 // Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
 124 // preprocessor will continue to expand it to
 125 //
 126 //       ... typename T ...
 127 //
 128 // This technique conforms to the C++ standard and is portable.  It
 129 // allows us to implement action templates using O(N) code, where N is
 130 // the maximum number of template/value parameters supported.  Without
 131 // using it, we'd have to devote O(N^2) amount of code to implement all
 132 // combinations of m and n.
 133
 134 // Declares the template parameters.

 537 // The InvokeArgument<N>(a1, a2, ..., a_k) action invokes the N-th
 538 // (0-based) argument, which must be a k-ary callable, of the mock
 539 // function, with arguments a1, a2, ..., a_k.
 540 //
 541 // Notes:
 542 //
 543 //   1. The arguments are passed by value by default.  If you need to
 544 //   pass an argument by reference, wrap it inside std::ref().  For
 545 //   example,
 546 //
 547 //     InvokeArgument<1>(5, string("Hello"), std::ref(foo))
 548 //
 549 //   passes 5 and string("Hello") by value, and passes foo by
 550 //   reference.
 551 //
 552 //   2. If the callable takes an argument by reference but std::ref() is
 553 //   not used, it will receive the reference to a copy of the value,
 554 //   instead of the original value.  For example, when the 0-th
 555 //   argument of the mock function takes a const string&, the action
 556 //
 557 //     InvokeArgument<0>(string("Hello"))
 558 //
 559 //   makes a copy of the temporary string("Hello") object and passes a
 560 //   reference of the copy, instead of the original temporary object,
 561 //   to the callable.  This makes it easy for a user to define an
 562 //   InvokeArgument action from temporary values and have it performed
 563 //   later.
