◆ operator<<()

std::ostream& OpenMS::operator<< ( std::ostream &  os,
const Exception::BaseException e 
)

Output operator for exceptions.

All OpenMS exceptions can be printed to an arbitrary output stream. Information written contains the exception class, the error message, and the location (file, line number). The following code block can thus be used to catch any OpenMS exceptions and convert them to human readable information:

try
{
.... // some code which potentially throws an exception
}
catch (Exception::Exception e)
{
Log.error() << "caught exception: " << e << std::endl;
}
