Detailed Description

class Dune::DebugStream< thislevel, dlevel, alevel, activator >
class Dune::DebugStream< thislevel, dlevel, alevel, activator >
Generic class to implement debug output streams.
The main function of a DebugStream is to provide output in a standard ostream fashion that is fully deactivated if the level of the stream does not meet the current requirements. More information in Debug output
- Parameters
-
thislevel this level dlevel level needed for any output to happen alevel level needed to switch activation flag on activator template describing the activation policy
- Todo:
- Fix visibility of internal data
