  41. // Sometimes you want to give an action explicit template parameters
  42. // that cannot be inferred from its value parameters. ACTION() and
  43. // ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
  44. // and can be viewed as an extension to ACTION() and ACTION_P*().
  45. //
  46. // The syntax:
  47. //
  48. // ACTION_TEMPLATE(ActionName,
  49. // HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
  50. // AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
  51. //
  52. // defines an action template that takes m explicit template
  53. // parameters and n value parameters. name_i is the name of the i-th
  54. // template parameter, and kind_i specifies whether it's a typename,
  55. // an integral constant, or a template. p_i is the name of the i-th
  56. // value parameter.
  57. //
  58. // Example:
  59. //
  60. // // DuplicateArg<k, T>(output) converts the k-th argument of the mock
  61. // // function to type T and copies it to *output.
  62. // ACTION_TEMPLATE(DuplicateArg,
  63. // HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
  64. // AND_1_VALUE_PARAMS(output)) {
  65. // *output = T(::std::get<k>(args));
  66. // }
  67. // ...
  68. // int n;
  69. // EXPECT_CALL(mock, Foo(_, _))
  70. // .WillOnce(DuplicateArg<1, unsigned char>(&n));
  71. //
  72. // To create an instance of an action template, write:
  73. //
  74. // ActionName<t1, ..., t_m>(v1, ..., v_n)
  75. //
  76. // where the ts are the template arguments and the vs are the value
  77. // arguments. The value argument types are inferred by the compiler.
  78. // If you want to explicitly specify the value argument types, you can
  79. // provide additional template arguments:
  80. //
  81. // ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
  82. //
  83. // where u_i is the desired type of v_i.
  84. //
  85. // ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
  86. // number of value parameters, but not on the number of template
  87. // parameters. Without the restriction, the meaning of the following
  88. // is unclear:
  89. //
  90. // OverloadedAction<int, bool>(x);
  91. //
  92. // Are we using a single-template-parameter action where 'bool' refers
  93. // to the type of x, or are we using a two-template-parameter action
  94. // where the compiler is asked to infer the type of x?
  95. //
  96. // Implementation notes:
  97. //
  98. // GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
  99. // GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
  100. // implementing ACTION_TEMPLATE. The main trick we use is to create
  101. // new macro invocations when expanding a macro. For example, we have
  102. //
  103. // #define ACTION_TEMPLATE(name, template_params, value_params)
  104. // ... GMOCK_INTERNAL_DECL_##template_params ...
  105. //
  106. // which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
  107. // to expand to
  108. //
  109. // ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
  110. //
  111. // Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
  112. // preprocessor will continue to expand it to
  113. //
  114. // ... typename T ...
  115. //
  116. // This technique conforms to the C++ standard and is portable. It
  117. // allows us to implement action templates using O(N) code, where N is
  118. // the maximum number of template/value parameters supported. Without
  119. // using it, we'd have to devote O(N^2) amount of code to implement all
  120. // combinations of m and n.
