Question

我有一个成员函数，引用了数组输出参数，我想在谷歌模拟中使用它，但它不起作用。

班级：

class Class
{
  // returns: number of the rewritten elements in the array
  int foo(Struct (&bar)[ArraySize]) const;
};

模拟课程：

class MockClass : public Class
{
  MOCK_CONST_METHOD1(foo, int(Struct (&)[ArraySize]));
};

当我想使用它时，我写下以下内容：

ON_CALL(mMockClass, foo(_))
  .WillByDefault( DoAll( SetArgReferee<0>(mBar)
                       , Return(5)
                       )
                );

mBar是一个合适的Struct（Struct mBar[ArraySize];）数组。当我编译它时，我收到以下错误消息：

../../../../vendor/gmock-1.7.0/include/gmock/gmock-more-actions.h: In member
function ‘typename testing::internal::Function<F>::Result
testing::SetArgRefereeActionP<k,
value_type>::gmock_Impl<F>::gmock_PerformImpl(const typename
testing::internal::Function<F>::ArgumentTuple&, arg0_type, arg1_type,
arg2_type, arg3_type, arg4_type, arg5_type, arg6_type, arg7_type, arg8_type,
arg9_type) const [with arg0_type = Struct (&)[32], arg1_type =
testing::internal::ExcessiveArg, arg2_type = testing::internal::ExcessiveArg,
arg3_type = testing::internal::ExcessiveArg, arg4_type =

我很抱歉错误消息格式。据我所知，编译器的问题是它假设对数组的引用但它得到一个指针。我错了什么？

更新：解决方案

对于传递类型数组SetArrayArgument<N>(first, last)的参数应该使用。

将源范围[first，last]中的元素复制到指向的数组通过第N个（从0开始）的参数，它可以是指针或迭代器。该操作不会获取所有元素的所有权来源范围
