类 stream_holder - Boost C++ 函数库

类 stream_holder

boost::unit_test::runtime_config::stream_holder

提要

// In header: <boost/test/unit_test_parameters.hpp>


class stream_holder {
public:
  // member classes/structs/unions

  struct callback_cleaner {

    // public member functions
    callback_cleaner(boost::function< void()>);
    ~callback_cleaner();

    // public data members
    boost::function< void()> m_cleaner_callback;
    std::ofstream m_file;
  };

  // public member functions
  explicit stream_holder(std::ostream & = std::cout);
  void setup(const const_string &, 
             boost::function< void()> const & = boost::function< void()>());
  std::ostream & ref() const;
};

描述

`stream_holder` 公有成员函数

explicit stream_holder(std::ostream & default_stream = std::cout);

void setup(const const_string & stream_name, 
           boost::function< void()> const & cleaner_callback = boost::function< void()>());

```
std::ostream & ref() const;
```
