Detailed Description

template<DebugLevel thislevel = 1, DebugLevel dlevel = 1, DebugLevel alevel = 1, template< DebugLevel, DebugLevel > class activator = greater_or_equal>
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
thislevelthis level
dlevellevel needed for any output to happen
alevellevel needed to switch activation flag on
activatortemplate describing the activation policy
Todo:
Fix visibility of internal data
