Member Function Documentation

void clear ( )
void start ( )
void stop ( )
double usertime ( ) const
inline

total amount of second spent in user mode.

Returns
the user time elapsed between the latest start() and the latest stop().
Precondition
stop() is called before.
Examples:
examples/FiniteField/gfq_atomic.C, and examples/FiniteField/zpz_atomic.C.
double systime ( ) const
inline

total amount of second spent in system mode.

Returns
the system time elapsed between the latest start() and the latest stop().
Precondition
stop() is called before.
double realtime ( ) const
inline

real total amount of second spent.

Returns
the real total time elapsed between the latest start() and the latest stop().
Precondition
stop() is called before.
double userElapsedTime ( )
inline

User mode time spent since start.

A call to stop() is useless.

Returns
elpased time (in seconds) since start() in user mode.
double sysElapsedTime ( )
inline

System mode time spent since start.

A call to stop() is useless.

Returns
elpased time (in seconds) since start() in system mode.
double realElapsedTime ( )
inline

real total amount of second spent since start.

A call to stop() is useless.

Returns
elpased time (in seconds) since start().
