Detailed Description

Debugging output.

Represents a debugging output, i.e. an output stream which can subscribe to channels.

There is two default output:

• console which points to std::cerr
• journal which points to the ``journal'' file in the debugging prefix */ class HPP_UTIL_DLLAPI Output { public: explicit Output(); virtual ~Output();

virtual void write(const Channel& channel, char const* file, int line, char const* function, const std::string& data) = 0;

virtual void write(const Channel& channel, char const* file, int line, char const* function, const std::stringstream& data) = 0;

protected: std::ostream& writePrefix(std::ostream& stream, const Channel& channel, char const* file, int line, char const* function); };

/** Receive debugging information.

Receive debugging information and forward it to its subscribers.

By default, there is four channels:

• error for fatal problems
• warning for non-fatal problems
• notice for user information
• info for technical information and debugging output
