|read_msg () const|
As described in workflow, processing the message is composed of 2 things:
The logger class has 2 template parameters:
|gather_msg||A new gather instance is created each time a message is written. The |
|write_msg||This is the object that does the second step - the writing of the message. It can be a simple functor. Or, it can be a more complex object that contains logic of how the message is to be further formatted, and written to multiple destinations. You can implement your own |
The logger forwards the gathering of the message to the
gather_msg class. Once all message is gathered, it's passed on to the writer. This is usually done through a macro.
