Detailed Description

Computes the time passed between two points in 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.

Member Typedef Documentation

typedef unsigned long itk::TimeProbe::CountType

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

Definition at line 51 of file itkTimeProbe.h.

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

overridevirtual

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

Implements itk::ResourceProbe< RealTimeClock::TimeStampType, RealTimeClock::TimeStampType >.

virtual const RealTimeClock* itk::TimeProbe::GetRealTimeClock ( ) const

virtual

Get a handle to m_RealTimeClock.

itk::TimeProbe::itkLegacyMacro

(

TimeStampType 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.
