Member Function Documentation

virtual const char* vl::Log::className ( ) [inline, virtual]

Returns the name of the class.

Reimplemented from vl::Object.

Reimplemented in vl::StandardLog.

Definition at line 59 of file Log.hpp.

virtual void vl::Log::printImplementation	(	ELogLevel	level,
		const String &	message
	)		`[protected, pure virtual]`

Implemented in vl::StandardLog.

Referenced by bug(), debug(), error(), info(), print(), and warning().

static void vl::Log::setLogMutex ( IMutex * mutex ) [inline, static]

The mutex used to synchronize concurrent calls to the log functions.

You should always install a log mutex when using VL in multi-threaded applications.

void Log::print ( const String & message ) [static]

Synchronize log across threads.
