Member Function Documentation

void clear

(

)

Clear timer.

Everything reset to 0. This need not be called before the first start since the constructor does it.

Examples:

examples/FiniteField/gfq_atomic.C, examples/FiniteField/zpz_atomic.C, examples/Integer/iexponentiation.C, examples/Integer/ifactor.C, examples/Integer/ifactor_lenstra.C, examples/Integer/igcd.C, examples/Integer/igcdext.C, examples/Integer/ilcm.C, examples/Integer/ispower.C, examples/Integer/isprime.C, examples/Integer/isproot.C, examples/Integer/lambda.C, examples/Integer/lambda_inv.C, examples/Integer/nb_primes.C, examples/Integer/nextprime.C, examples/Integer/order.C, examples/Integer/phi.C, examples/Integer/prevprime.C, examples/Integer/primitiveelement.C, examples/Integer/primitiveroot.C, examples/Integer/probable_primroot.C, examples/Integer/ProbLucas.C, examples/Integer/RSA_breaking.C, examples/Integer/RSA_decipher.C, examples/Integer/RSA_encipher.C, examples/Integer/RSA_keys_generator.C, examples/Polynomial/highorder.C, examples/Polynomial/interpolate.C, examples/Polynomial/isirred.C, examples/Polynomial/isprimitive.C, examples/Polynomial/pol_eval.C, examples/Polynomial/pol_factor.C, examples/Polynomial/PolynomialCRT.C, and examples/Rational/iratrecon.C.

void start

(

)

Start timer.

Starts the timer. If called after another start() or a stop(), it sets the timer to a totally fresh new start.

Examples:

examples/FiniteField/gfq_atomic.C, examples/FiniteField/zpz_atomic.C, examples/Integer/iexponentiation.C, examples/Integer/ifactor.C, examples/Integer/ifactor_lenstra.C, examples/Integer/igcd.C, examples/Integer/igcdext.C, examples/Integer/ilcm.C, examples/Integer/ispower.C, examples/Integer/isprime.C, examples/Integer/isproot.C, examples/Integer/lambda.C, examples/Integer/lambda_inv.C, examples/Integer/ModularSquareRoot.C, examples/Integer/nb_primes.C, examples/Integer/nextprime.C, examples/Integer/order.C, examples/Integer/phi.C, examples/Integer/prevprime.C, examples/Integer/primitiveelement.C, examples/Integer/primitiveroot.C, examples/Integer/probable_primroot.C, examples/Integer/ProbLucas.C, examples/Integer/RSA_breaking.C, examples/Integer/RSA_decipher.C, examples/Integer/RSA_encipher.C, examples/Integer/RSA_keys_generator.C, examples/Polynomial/highorder.C, examples/Polynomial/interpolate.C, examples/Polynomial/isirred.C, examples/Polynomial/isprimitive.C, examples/Polynomial/pol_eval.C, examples/Polynomial/pol_factor.C, examples/Polynomial/PolynomialCRT.C, and examples/Rational/iratrecon.C.

void stop

(

)

Stop timer.

Stops the timer. The time since the previous start() is stored. If called again, stop() will store the time since the previous start() again, acting as a pause().

Precondition:

start() should have been called before...

Examples:

examples/FiniteField/gfq_atomic.C, examples/FiniteField/zpz_atomic.C, examples/Integer/iexponentiation.C, examples/Integer/ifactor.C, examples/Integer/ifactor_lenstra.C, examples/Integer/igcd.C, examples/Integer/igcdext.C, examples/Integer/ilcm.C, examples/Integer/ispower.C, examples/Integer/isprime.C, examples/Integer/isproot.C, examples/Integer/lambda.C, examples/Integer/lambda_inv.C, examples/Integer/ModularSquareRoot.C, examples/Integer/nb_primes.C, examples/Integer/nextprime.C, examples/Integer/order.C, examples/Integer/phi.C, examples/Integer/prevprime.C, examples/Integer/primitiveelement.C, examples/Integer/primitiveroot.C, examples/Integer/probable_primroot.C, examples/Integer/ProbLucas.C, examples/Integer/RSA_breaking.C, examples/Integer/RSA_decipher.C, examples/Integer/RSA_encipher.C, examples/Integer/RSA_keys_generator.C, examples/Polynomial/highorder.C, examples/Polynomial/interpolate.C, examples/Polynomial/isirred.C, examples/Polynomial/isprimitive.C, examples/Polynomial/pol_eval.C, examples/Polynomial/pol_factor.C, examples/Polynomial/PolynomialCRT.C, and examples/Rational/iratrecon.C.

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().
