Detailed Description

Class for computing the time passed between two points in the code.

This class allows the user to trace the time passed between the execution of two pieces of code. It can be started and stopped in order to evaluate the execution over multiple passes. The values of time are taken from the RealTimeClock.

See also:: RealTimeClock

Member Typedef Documentation

typedef unsigned long itk::TimeProbe::CountType

Type for counting how many times the probe has been started and stopped.

Reimplemented from itk::ResourceProbe< ValueType, MeanType >.

typedef RealTimeClock::TimeStampType itk::TimeProbe::TimeStampType

Type for measuring time. See the RealTimeClock class for details on the precision and units of this clock signal

Member Function Documentation

virtual RealTimeClock::TimeStampType itk::TimeProbe::GetInstantValue ( void ) const [virtual]

Get the current time. Warning: the returned value is not the elapsed time since the last Start() call.

Implements itk::ResourceProbe< ValueType, MeanType >.

template<class ValueType, class MeanType>

MeanType itk::ResourceProbe< ValueType, MeanType >::GetMean ( void ) const [inherited]

Returns the average value changes between the starts and stops of the probe. Stop() has to be called at least once, returns 0 otherwise.

TimeStampType itk::TimeProbe::GetMeanTime ( void ) const

Returns the average times passed between the starts and stops of the probe. See the RealTimeClock for details on the precision and units of this time value. Obsolete method kept for backward compatibility, use Probe::GetMean() instead.
