Typedef Documentation

Clock

using Clock = std::chrono::high_resolution_clock

Definition at line 9 of file timing.h.

TPoint

using TPoint = std::chrono::time_point<Clock>

Definition at line 10 of file timing.h.

Function Documentation

tic()

auto tic ( )

inline

Starts stopwatch timer. Use as

tic(); myfunction(...) ; double tsec = toc();  

The timining can be nested and the recent time point is stored on top of the stack.

Returns

recent time point

See also

toc

Definition at line 24 of file timing.h.

Here is the caller graph for this function:

toc()

double toc ( TPoint const &  t_b = MyStopWatch.top() )

inline

Returns the elapsed time from stopwatch.

The time point from top of the stack is used if time point t_b is not passed as input parameter. Use as

tic(); myfunction(...) ; double tsec = toc();  

or as

auto t_b = tic(); myfunction(...) ; double tsec = toc(t_b);  

The last option is to be used in the case of non-nested but overlapping time measurements.

Parameters

[in]

t_b

start time of some stop watch

Returns

elapsed time in seconds.
