  90. // ACTION(name) { statements; }

  92. // will define an action with the given name that executes the

  95. // refer to the K-th (0-based) argument of the mock function by
  96. // 'argK', and refer to its type by 'argK_type'. For example:
  97. //
  98. // ACTION(IncrementArg1) {
  99. // arg1_type temp = arg1;
  100. // return ++(*temp);
  101. // }
  102. //
  103. // allows you to write
  104. //
  105. // ...WillOnce(IncrementArg1());
  106. //
  107. // You can also refer to the entire argument tuple and its type by
  108. // 'args' and 'args_type', and refer to the mock function type and its
  109. // return type by 'function_type' and 'return_type'.
  110. //
  111. // Note that you don't need to specify the types of the mock function
  112. // arguments. However rest assured that your code is still type-safe:
  113. // you'll get a compiler error if *arg1 doesn't support the ++
  114. // operator, or if the type of ++(*arg1) isn't compatible with the
  115. // mock function's return type, for example.
  116. //
  117. // Sometimes you'll want to parameterize the action. For that you can use
  118. // another macro:
  119. //
  120. // ACTION_P(name, param_name) { statements; }
  121. //
  122. // For example:
  123. //
  124. // ACTION_P(Add, n) { return arg0 + n; }
  125. //
  126. // will allow you to write:
  127. //
  128. // ...WillOnce(Add(5));
  129. //
  130. // Note that you don't need to provide the type of the parameter
  131. // either. If you need to reference the type of a parameter named
  132. // 'foo', you can write 'foo_type'. For example, in the body of
  133. // ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
  134. // of 'n'.
  135. //
  136. // We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P$n to support
  137. // multi-parameter actions.
  138. //
  139. // For the purpose of typing, you can view
  140. //
  141. // ACTION_Pk(Foo, p1, ..., pk) { ... }
  142. //
  143. // as shorthand for
  144. //
  145. // template <typename p1_type, ..., typename pk_type>
  146. // FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
  147. //
  148. // In particular, you can provide the template type arguments
  149. // explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
  150. // although usually you can rely on the compiler to infer the types
  151. // for you automatically. You can assign the result of expression
  152. // Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
  153. // pk_type>. This can be useful when composing actions.
  154. //
  155. // You can also overload actions with different numbers of parameters:
  156. //
  157. // ACTION_P(Plus, a) { ... }
  158. // ACTION_P2(Plus, a, b) { ... }
  159. //
  160. // While it's tempting to always use the ACTION* macros when defining
  161. // a new action, you should also consider implementing ActionInterface
  162. // or using MakePolymorphicAction() instead, especially if you need to
  163. // use the action a lot. While these approaches require more work,
  164. // they give you more control on the types of the mock function
  165. // arguments and the action parameters, which in general leads to
  166. // better compiler error messages that pay off in the long run. They
  167. // also allow overloading actions based on parameter types (as opposed
  168. // to just based on the number of parameters).
  169. //
  170. // CAVEAT:
  171. //
  172. // ACTION*() can only be used in a namespace scope as templates cannot be
  173. // declared inside of a local class.
  174. // Users can, however, define any local functors (e.g. a lambda) that
  175. // can be used as actions.

  201. // template parameter, and kind_i specifies whether it's a typename,
  202. // an integral constant, or a template. p_i is the name of the i-th
  203. // value parameter.
  204. //
  205. // Example:

  221. // ActionName<t1, ..., t_m>(v1, ..., v_n)
  222. //
  223. // where the ts are the template arguments and the vs are the value
  224. // arguments. The value argument types are inferred by the compiler.
  225. // If you want to explicitly specify the value argument types, you can
  226. // provide additional template arguments:
  227. //
  228. // ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
  229. //
  230. // where u_i is the desired type of v_i.
  231. //
  232. // ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
  233. // number of value parameters, but not on the number of template
  234. // parameters. Without the restriction, the meaning of the following
  235. // is unclear:
  236. //
  237. // OverloadedAction<int, bool>(x);
  238. //
  239. // Are we using a single-template-parameter action where 'bool' refers
  240. // to the type of x, or are we using a two-template-parameter action
  241. // where the compiler is asked to infer the type of x?
  242. //
  243. // Implementation notes:
  244. //
  245. // GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
  246. // GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
  247. // implementing ACTION_TEMPLATE. The main trick we use is to create
  248. // new macro invocations when expanding a macro. For example, we have
  249. //
  250. // #define ACTION_TEMPLATE(name, template_params, value_params)
  251. // ... GMOCK_INTERNAL_DECL_##template_params ...
  252. //
  253. // which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
  254. // to expand to
  255. //
  256. // ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
  257. //
  258. // Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
  259. // preprocessor will continue to expand it to
  260. //
  261. // ... typename T ...
  262. //
  263. // This technique conforms to the C++ standard and is portable. It
  264. // allows us to implement action templates using O(N) code, where N is

  467. //
  468. // 1. The arguments are passed by value by default. If you need to
  469. // pass an argument by reference, wrap it inside ByRef(). For
  470. // example,
  471. //
  472. // InvokeArgument<1>(5, string("Hello"), ByRef(foo))

  475. // reference.

  477. // 2. If the callable takes an argument by reference but ByRef() is
  478. // not used, it will receive the reference to a copy of the value,
  479. // instead of the original value. For example, when the 0-th
  480. // argument of the mock function takes a const string&, the action
  481. //
  482. // InvokeArgument<0>(string("Hello"))
  483. //

  485. // reference of the copy, instead of the original temporary object,
