Detailed Description

A DebugSlave uses a link to another master Debugable to provide its log and bug services.

If there is no master, the slave always return a null Dv::ostream_ptr and a debug level of 0.

Note that the liberal use of const_cast. The idea is that adding debug manipulation to existing code should not generate const-correctness errors.

Constructor & Destructor Documentation

Dv::DebugSlave::DebugSlave	(	unsigned int	minimal_debug_level = `0`,
		Debugable *	master = `0`
	)			`[inline]`

Constructor.

Parameters:

	minimal_debug_level	only if the master's debug level is at least this number will the master's Dv::ostream_ptr be returned by the Dv::DebugSlave::logif and Dv::DebugSlave::log member functions.
	master	to which the object will be connected. This can also be done later using Dv::DebugSlave::set_debug_master

virtual ostream_ptr& Dv::DebugSlave::logif ( bool condition ) const [inline, virtual]

Return an Dv::ostream_ptr to write debug or log info on.

Parameters:

condition

a non-null Dv::ostream_ptr will be returned only if this condition is true and the master debug level is at least the treshold specified in the constructor.

Returns:: the master Dv::ostream_ptr if the condition is true and the master debug level is at least the treshold specified in the constructor.; a null Dv::ostream_ptr if the condition is false or the master debug level is less than the treshold specified in the constructor.
