Using custom Writers and Timers

If the supplemented classes for use as MyDBImpl and MyTimerImpl are not sufficient, a guide for own implementations is given.

MyDBImpl

MyDBImpl needs two member functions. The first reads a host from the database and the second stores a test and its associated parameters in the database.

Custom Writer

class MyDBImpl
{  
  public:
    // Reads a host from the HOST-table with the given HostName
    const viennaprofiler::Host getHost(std::string hostName) {...}
    
    // Inserts the given benchmark and the given parameters in
    // the TEST-table respectively the PARAMETER-table
    void insertTest(Benchmark const & test, std::vector<Parameter> parameters) {...}
};

MyTimerImpl

The concept for MyTimerImpl requires three member-functions. The first one to start the timer, the second one to stop the timer and the last one to acquire the elapsed time.

Custom Timer

class MyTimerImpl
{
  public:
    // Starts the timer
    void start() {...}
 
    // Stops the timer
    void stop() {...}
 
    // Gives the elapsed time between start() and stop() in "seconds"
    double elapsed() const {...}
};
