Hi Dean,
While looking at the documentation I see that the handler is originally
designed to be a function object.
That's nice, so the application developer can:
- Provide a function if the case is a simple one, or
- If the implementation needs state information, provide a class with a
function call operator overloaded.
However, the call to the Handler::log() brakes that simplicity, the handler is
forced to be a class.
Below are the possible solutions to this problem, with each having their own
pro & cons (mostly taste related).
1. Provide an extra error argument to the function.
2. Handler::log() assumption is fine, let's force the implementation to be a
class with specific
handle_data() and handle_error() functions.
3. Provide 2 different handler functions, one for data and one for error.
So I have provided an interface to handle all. I think being easy is nothing to
do with this.
Here, the interface to the application developer is easy, and the
implementation is a little
bit complicated.
By the way there is no need of the template argument Handler in this
implementation.
