这是我遇到的错误

class COMMON_CCA_INTERFACE IpuCCAInterfaceBase : public ICCAOperations
{
private:

    vector<int> _remaining_run_kernels_uuids;
}

这是头文件

cpp 负责人

IpuCCAInterfaceBase::IpuCCAInterfaceBase()
{
   
}

我们正在使用 klocworks 20.1 解决此错误的推荐方法是什么？

向量稍后将在不同的函数中初始化和填充。但是当加载 class 时里面没有数据。

Answer 1

也许 Klockwork 要求您显式初始化向量，例如在构造函数初始化列表中：

IpuCCAInterfaceBase::IpuCCAInterfaceBase()
    : _remaining_run_kernels_uuids{ }
{
}

话虽如此，我认为该消息是误报，因为即使没有这个，向量也应该隐式默认构造（并因此初始化）。
