// Sometimes you want to give an action explicit template parameters
// that cannot be inferred from its value parameters. ACTION() and
// ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
// and can be viewed as an extension to ACTION() and ACTION_P*().
//
// The syntax:
//
// ACTION_TEMPLATE(ActionName,
// HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
// AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
//
// defines an action template that takes m explicit template
// parameters and n value parameters. name_i is the name of the i-th
// template parameter, and kind_i specifies whether it's a typename,
// an integral constant, or a template. p_i is the name of the i-th
// value parameter.
//
// Example:
//
// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
// // function to type T and copies it to *output.
// ACTION_TEMPLATE(DuplicateArg,
// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
// AND_1_VALUE_PARAMS(output)) {
// *output = T(::std::get<k>(args));
// }
// ...
// int n;
// EXPECT_CALL(mock, Foo(_, _))
// .WillOnce(DuplicateArg<1, unsigned char>(&n));
//
// To create an instance of an action template, write:
//
// ActionName<t1, ..., t_m>(v1, ..., v_n)
//
// where the ts are the template arguments and the vs are the value
// arguments. The value argument types are inferred by the compiler.
// If you want to explicitly specify the value argument types, you can
// provide additional template arguments:
//
// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
//
// where u_i is the desired type of v_i.
//
// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
// number of value parameters, but not on the number of template
// parameters. Without the restriction, the meaning of the following
// is unclear:
//
// OverloadedAction<int, bool>(x);
//
// Are we using a single-template-parameter action where 'bool' refers
// to the type of x, or are we using a two-template-parameter action
// where the compiler is asked to infer the type of x?
//
// Implementation notes:
//
// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
// implementing ACTION_TEMPLATE. The main trick we use is to create
// new macro invocations when expanding a macro. For example, we have
//
// #define ACTION_TEMPLATE(name, template_params, value_params)
// ... GMOCK_INTERNAL_DECL_##template_params ...
//
// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
// to expand to
//
// ... 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. It
// allows us to implement action templates using O(N) code, where N is
// the maximum number of template/value parameters supported. Without
// using it, we'd have to devote O(N^2) amount of code to implement all
// combinations of m and n.
// Declares the template parameters.

// (0-based) argument, which must be a k-ary callable, of the mock
// function, with arguments a1, a2, ..., a_k.
//
// Notes:
//
// 1. The arguments are passed by value by default. If you need to
// pass an argument by reference, wrap it inside std::ref(). For
// example,
//
// InvokeArgument<1>(5, string("Hello"), std::ref(foo))
//
// passes 5 and string("Hello") by value, and passes foo by
// reference.
//
// 2. If the callable takes an argument by reference but std::ref() is
// not used, it will receive the reference to a copy of the value,
// instead of the original value. For example, when the 0-th
// argument of the mock function takes a const string&, the action
//
// InvokeArgument<0>(string("Hello"))
//
// makes a copy of the temporary string("Hello") object and passes a
// reference of the copy, instead of the original temporary object,
// to the callable. This makes it easy for a user to define an
// InvokeArgument action from temporary values and have it performed
// later.
