You can assign the result of expression 331// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ..., 332// pk_type>. This can be useful when composing actions. 333// 334// You can also overload actions with different numbers of parameters: 335// 336// ACTION_P(Plus, a) { ... } 337// ACTION_P2(Plus, a, b) { ... } 338// 339// While it's tempting to always use the ACTION* macros when defining 340// a new action, you should also consider implementing ActionInterface 341// or using MakePolymorphicAction() instead, especially if you need to 342// use the action a lot. While these approaches require more work, 343// they give you more control on the types of the mock function 344// arguments and the action parameters, which in general leads to 345// better compiler error messages that pay off in the long run. They 346// also allow overloading actions based on parameter types (as opposed 347// to just based on the number of parameters). 348// 349// CAVEAT: 350// 351// ACTION*() can only be used in a namespace scope.

The main trick we use is to create 432// new macro invocations when expanding a macro. For example, we have 433// 434// #define ACTION_TEMPLATE(name, template_params, value_params) 435// ... GMOCK_INTERNAL_DECL_##template_params ... 436// 437// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...) 438// to expand to 439// 440// ...
