Detailed Description

A small class to help profiling.

It allows the calculation of the elapsed time (in milliseconds) between its creation (or the last call to Start() ) and the last call to Stop()

Constructor & Destructor Documentation

◆ PROF_TIMER() [1/2]

PROF_TIMER::PROF_TIMER	(	const std::string &	aName,
		bool	aAutostart = `true`
	)

inline

Create a PROF_COUNTER for measuring an elapsed time in milliseconds.

Parameters

aName	a string that will be printed in message.
aAutostart	true (default) to immediately start the timer

Definition at line 57 of file profile.h.

References Start().

◆ PROF_TIMER() [2/2]

PROF_TIMER::PROF_TIMER ( )

inline

Create a PROF_COUNTER for measuring an elapsed time in milliseconds.

The counter is started and the string to print in message is left empty.

Definition at line 69 of file profile.h.

References Start().

Member Function Documentation

◆ msecs()

double PROF_TIMER::msecs ( bool aSinceLast = false )

inline

Parameters

aSinceLast only get the time since the last time the time was read.

Returns: the elapsed time in ms since the timer was started.

◆ Show()

void PROF_TIMER::Show ( std::ostream & aStream = std::cerr )

inline

Print the elapsed time (in a suitable unit) to a stream.

The unit is automatically chosen from ns, us, ms and s, depending on the size of the current count.

Parameters

the	stream to print to.

◆ SinceStart()

template<typename DURATION >

DURATION PROF_TIMER::SinceStart ( bool aSinceLast = false )

inline

Returns: the time since the timer was started. If the timer is stopped, the duration is from the start time to the time it was stopped, else it is to the current time.
