For that you can use -// another macro: -// -// ACTION_P(name, param_name) { statements; } -// -// For example: -// -// ACTION_P(Add, n) { return arg0 + n; } -// -// will allow you to write: -// -// ...WillOnce(Add(5)); -// -// Note that you don't need to provide the type of the parameter -// either. If you need to reference the type of a parameter named -// 'foo', you can write 'foo_type'. For example, in the body of -// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type -// of 'n'. -// -// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support -// multi-parameter actions. -// -// For the purpose of typing, you can view -// -// ACTION_Pk(Foo, p1, ..., pk) { ... } -// -// as shorthand for -// -// template -// FooActionPk Foo(p1_type p1, ..., pk_type pk) { ... } -// -// In particular, you can provide the template type arguments -// explicitly when invoking Foo(), as in Foo(5, false); -// although usually you can rely on the compiler to infer the types -// for you automatically. You can assign the result of expression -// Foo(p1, ..., pk) to a variable of type FooActionPk. This can be useful when composing actions. -// -// You can also overload actions with different numbers of parameters: -// -// ACTION_P(Plus, a) { ... } -// ACTION_P2(Plus, a, b) { ... } -// -// While it's tempting to always use the ACTION* macros when defining -// a new action, you should also consider implementing ActionInterface -// or using MakePolymorphicAction() instead, especially if you need to -// use the action a lot. While these approaches require more work, -// they give you more control on the types of the mock function -// arguments and the action parameters, which in general leads to -// better compiler error messages that pay off in the long run. They -// also allow overloading actions based on parameter types (as opposed -// to just based on the number of parameters). -// -// CAVEAT: -// -// ACTION*() can only be used in a namespace scope. The reason is -// that C++ doesn't yet allow function-local types to be used to -// instantiate templates. The up-coming C++0x standard will fix this. -// Once that's done, we'll consider supporting using ACTION*() inside -// a function. -// -// MORE INFORMATION: -// -// To learn more about using these macros, please search for 'ACTION' -// on http://code.google.com/p/googlemock/wiki/CookBook. - -// An internal macro needed for implementing ACTION*(). -#define GMOCK_ACTION_ARG_TYPES_AND_NAMES_UNUSED_\ - const args_type& args GTEST_ATTRIBUTE_UNUSED_, \ - arg0_type arg0 GTEST_ATTRIBUTE_UNUSED_, \ - arg1_type arg1 GTEST_ATTRIBUTE_UNUSED_, \ - arg2_type arg2 GTEST_ATTRIBUTE_UNUSED_, \ - arg3_type arg3 GTEST_ATTRIBUTE_UNUSED_, \ - arg4_type arg4 GTEST_ATTRIBUTE_UNUSED_, \ - arg5_type arg5 GTEST_ATTRIBUTE_UNUSED_, \ - arg6_type arg6 GTEST_ATTRIBUTE_UNUSED_, \ - arg7_type arg7 GTEST_ATTRIBUTE_UNUSED_, \ - arg8_type arg8 GTEST_ATTRIBUTE_UNUSED_, \ - arg9_type arg9 GTEST_ATTRIBUTE_UNUSED_ - -// Sometimes you want to give an action explicit template parameters -// that cannot be inferred from its value parameters.

GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ... -// -// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the -// preprocessor will continue to expand it to -// -// ... typename T ... -// -// This technique conforms to the C++ standard and is portable.
