Detailed Description

template<typename ValueType, typename MeanType>
class itk::ResourceProbe< ValueType, MeanType >

Computes the change of a value between two points in code.

This class is the base class of all the probes (time, memory, etc.) between the execution of two pieces of code. It can be started and stopped in order to evaluate the execution over multiple passes.

template<typename ValueType, typename MeanType>

virtual ValueType itk::ResourceProbe< ValueType, MeanType >::GetInstantValue ( void  ) const

pure virtual

Returns the instant value of the probed system.

Implemented in itk::TimeProbe, and itk::MemoryProbe.

template<typename ValueType, typename MeanType>

MeanType itk::ResourceProbe< ValueType, MeanType >::GetMean

(

void

)

const

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

template<typename ValueType, typename MeanType>

CountType itk::ResourceProbe< ValueType, MeanType >::GetNumberOfStarts

(

void

)

const

Returns the number of times that the probe has been started

template<typename ValueType, typename MeanType>

CountType itk::ResourceProbe< ValueType, MeanType >::GetNumberOfStops

(

void

)

const

Returns the number of times that the probe has been stopped

template<typename ValueType, typename MeanType>

ValueType itk::ResourceProbe< ValueType, MeanType >::GetTotal

(

void

)

const

Returns the accumulated value changes between the starts and stops of the probe

template<typename ValueType, typename MeanType>

std::string itk::ResourceProbe< ValueType, MeanType >::GetType

(

void

)

const

Returns the type probed value

template<typename ValueType, typename MeanType>

std::string itk::ResourceProbe< ValueType, MeanType >::GetUnit

(

void

)

const

Returns the unit probed value

template<typename ValueType, typename MeanType>

void itk::ResourceProbe< ValueType, MeanType >::Reset

(

void

)

Reset the probe

template<typename ValueType, typename MeanType>

void itk::ResourceProbe< ValueType, MeanType >::Start

(

void

)

Start counting the change of value

Referenced by itk::XMLFilterWatcher::StartFilter().

template<typename ValueType, typename MeanType>

void itk::ResourceProbe< ValueType, MeanType >::Stop

(

void

)

Stop counting the change of value.

If a matching Start() has not been called before, there is no effect.
