Detailed Description

template<typename T>
class AJAMovingAvg< T >

Class that maintains a moving average of a fixed number of T samples. Defaults to a maximum of 10 samples.

Definition at line 28 of file ajamovingavg.h.

Constructor & Destructor Documentation

AJAMovingAvg()

template<typename T >

AJAMovingAvg< T >::AJAMovingAvg ( const size_t  inMaxNumSamples = kDefaultMaxNumSamples )

inlineexplicit

Constructs me with the given sample capacity.

Parameters

[in]

inMaxNumSamples

Specifies the maximum number of samples to be stored.

Definition at line 39 of file ajamovingavg.h.

Member Function Documentation

addSample()

template<typename T >

void AJAMovingAvg< T >::addSample ( const T  inValue )

inline

Stores the given sample value. If my sample capacity is exceeded, my oldest sample is dropped.

Parameters

[in]

inValue

Specifies the new sample value.

Definition at line 49 of file ajamovingavg.h.

average()

template<typename T >

T AJAMovingAvg< T >::average ( void  ) const

inline

Returns

my recent average.

Definition at line 108 of file ajamovingavg.h.

averageF()

template<typename T >

double AJAMovingAvg< T >::averageF ( void  ) const

inline

Returns

my recent average as a double-precision floating-point value.

Definition at line 118 of file ajamovingavg.h.

isEmpty()

template<typename T >

bool AJAMovingAvg< T >::isEmpty ( void  ) const

inline

Returns

true if I'm empty.

Definition at line 98 of file ajamovingavg.h.

isFilled()

template<typename T >

bool AJAMovingAvg< T >::isFilled ( void  ) const

inline

Returns

true if I've received at least enough samples to fill my deque.

Definition at line 103 of file ajamovingavg.h.

isValid()

template<typename T >

bool AJAMovingAvg< T >::isValid ( void  ) const

inline

Returns

true if I'm valid.

Definition at line 93 of file ajamovingavg.h.

largestPossibleValue()

template<typename T >

static T AJAMovingAvg< T >::largestPossibleValue ( void  )

inlinestaticprotected

Definition at line 226 of file ajamovingavg.h.

maximum()

template<typename T >

T AJAMovingAvg< T >::maximum ( void  ) const

inline

Returns

the maximum value ever seen by addSample.

Definition at line 146 of file ajamovingavg.h.

minimum()

template<typename T >

T AJAMovingAvg< T >::minimum ( void  ) const

inline

Returns

the minimum value ever seen by addSample.

Definition at line 128 of file ajamovingavg.h.

numStoredSamples()

template<typename T >

size_t AJAMovingAvg< T >::numStoredSamples ( void  ) const

inline

Returns

the current number of samples I'm storing.

Definition at line 78 of file ajamovingavg.h.

Print()

template<typename T >

std::ostream& AJAMovingAvg< T >::Print ( std::ostream &  oss, const bool  inDetailed = false  ) const

inline

Writes my current state in a human-readable form into the given output stream.

Parameters

	oss	The output stream to write into.
[in]	inDetailed	Specify true to print detailed information about my state; otherwise just print my average value as a floating-point value. Defaults to false.

Definition at line 169 of file ajamovingavg.h.

recentMaximum()

template<typename T >

T AJAMovingAvg< T >::recentMaximum ( void  ) const

inline

Returns

the maximum value from my stored samples.

Definition at line 151 of file ajamovingavg.h.

recentMinimum()

template<typename T >

T AJAMovingAvg< T >::recentMinimum ( void  ) const

inline

Returns

the minimum value from my stored samples.

Definition at line 133 of file ajamovingavg.h.

reset()

template<typename T >

void AJAMovingAvg< T >::reset ( const size_t  inMaxNumSamples = kDefaultMaxNumSamples )

inline

Resets me with the given maximum number of samples.

Parameters

[in]

inMaxNumSamples

Specifies my new sample capacity.

Definition at line 66 of file ajamovingavg.h.

sampleCapacity()

template<typename T >

size_t AJAMovingAvg< T >::sampleCapacity ( void  ) const

inline
