Detailed Description

template<typename DURATION>
class SCOPED_PROF_TIMER< DURATION >

A simple RAII class to measure the time of an operation.

On construction, a timer is started, and on destruction, the timer is ended, and the time difference is written into the given duration.

For example:

DURATION duration; // select a duration type as needed { SCOPED_PROF_TIMER<DURATION> timer( duration ); timed_activity(); } // duration is now the time timed activity took

From C++17, with class template argument deduction, you should be able to omit the <DURATION>.

Member Function Documentation

◆ msecs()

double PROF_TIMER::msecs ( bool aSinceLast = false )

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 )

inlineinherited

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 )

inlineinherited

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.
