Detailed Description

measures the CPU time in C++ programs.

NAME: CPUclock - measures the CPU time in C++ programs

DESCRIPTION:

One can get the user time in absolute seconds, or the length of intervals can be measured (in seconds).

Constructor & Destructor Documentation

CPUclock::CPUclock ( )

The class has only one constructor which takes no arguments.

Member Function Documentation

double CPUclock::getInterval ( )

returns the length of the user+system time interval (in seconds) between the present call to getInterval and the last call to "initTime" or to "getInterval".

double CPUclock::getIntervalU ( )

as "getInterval", but only the user time is returned.

double CPUclock::getTime ( )

returns absolute user time in seconds

void CPUclock::initTime ( ) [inline]

start measuring the length of an interval (typically called prior to the computational job to be measured). In fact, "initTime" is just a call to "getInterval" - the purpose of the function is to make programs easier to read.

void CPUclock::lock ( ) [inline]

locks the time, that is, when this function is called, calls to "getInterval" will not reset the time each time the function is called.

bool CPUclock::locked ( ) const [inline]

returns true if timecounter is locked, and false otherwise.

void CPUclock::unlock ( ) [inline]

unlocks the time, that is, when this function is called, calls to "getInterval" will reset the time each time the function is called (default behaviour).
