fcl::detail::Profiler Class Reference

This is a simple thread-safe tool for counting time spent in various chunks of code. This is different from external profiling tools in that it allows the user to count time spent in various bits of code (sub-function granularity) or count how many times certain pieces of code are executed.

Classes
class	ScopedBlock
	This instance will call Profiler::begin() when constructed and Profiler::end() when it goes out of scope. More...
class	ScopedStart
	This instance will call Profiler::start() when constructed and Profiler::stop() when it goes out of scope. If the profiler was already started, this block's constructor and destructor take no action. More...

Public Member Functions
	Profiler (const Profiler &)=delete
Profiler &	operator= (const Profiler &)=delete
	Profiler (bool printOnDestroy=false, bool autoStart=false)
	Constructor. It is allowed to separately instantiate this class (not only as a singleton)
	~Profiler (void)
	Destructor.
void	start (void)
	Start counting time.
void	stop (void)
	Stop counting time.
void	clear (void)
	Clear counted time and events.
void	event (const std::string &name, const unsigned int times=1)
	Count a specific event for a number of times.
void	average (const std::string &name, const double value)
	Maintain the average of a specific value.
void	begin (const std::string &name)
	Begin counting time for a specific chunk of code.
void	end (const std::string &name)
	Stop counting time for a specific chunk of code.
void	status (std::ostream &out=std::cout, bool merge=true)
	Print the status of the profiled code chunks and events. Optionally, computation done by different threads can be printed separately.
bool	running (void) const
	Check if the profiler is counting time or not.
