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().
