Detailed Description

Each time series (GKTimeSerie) has an associated description. Two (or more) time series can share the same description if their data is compatible (same time intervals and duration, same data type).

Member Function Documentation

dimensions()

int GKTSDescription::dimensions

(

Returns max number of the dimensions used by TS with this description.

expand()

void GKTSDescription::expand

(

const QDateTime &

expandMaxMin()

void GKTSDescription::expandMaxMin

(

double

)

Recalculates the maximum and minimum values taking into account value (that is a value in that has been added to a time series).

findCommonDates()

static void GKTSDescription::findCommonDates ( const GKTSDescription *  t1, const GKTSDescription *  t2, QDateTime &  from, QDateTime &  to  )

static

Find common dates (from, to) in to Timeseries that have a common interval.

findCommonTimes()

static void GKTSDescription::findCommonTimes ( const GKTSDescription *  t1, const GKTSDescription *  t2, QTime &  from, QTime &  to  )

static

Find common times (from, to) in to Timeseries that have a common interval. The date in the date and time information is not used.

getAggregationType()

GK::AggregationType GKTSDescription::getAggregationType

(

)

const

When aggregating data, gives what is relevant: the mean or the sum.

getConversion()

const GK::Conversion GKTSDescription::getConversion

(

)

const

Units of this TS.

getCreateDescription()

static GKTSDescription * GKTSDescription::getCreateDescription ( GKColumn *  col, const QString &  uniqueName  )

static

Find (and create a new one if none is found) a TS description by uniqueName.

getDuration()

const GKTimeDuration GKTSDescription::getDuration

(

const GKTimeSerie *

)

const

Calculates the duration of a TS based on its from and to data or the interval.

getExtraInfo()

GKTimeSerie::ExtraInfo GKTSDescription::getExtraInfo

(

)

const

Has deviation or bands for each value in the time series?

getFromTime()

const QDateTime & GKTSDescription::getFromTime

(

)

const

getInterval() [1/2]

int GKTSDescription::getInterval

(

const QDateTime &

)

const

Returns the interval (the position in the time series array of value) in where time is truncated to the nearest integer.

If time is not in the interval -1 is returned.

getInterval() [2/2]

int GKTSDescription::getInterval

(

const QTime &

)

const

Returns the interval (the position in the time series array of value) in where time is truncated to the nearest integer. QDate info is not used in the from and to times, only the QTime part.

If time is not in the interval -1 is returned.

getIntervalTime()

const GKTimeDuration & GKTSDescription::getIntervalTime

(

)

const

getMaximum()

double GKTSDescription::getMaximum

(

)

const

Returns the maximum value of all the TS that uses this description.

getMinimum()

double GKTSDescription::getMinimum

(

)

const

Returns the minimum value of all the TS that uses this description.

getNullValue()

double GKTSDescription::getNullValue

(

)

const

Returns the NULL value for this TS description. Test firts if a NULL has been defined using GKTSDescription::hasNullValue

getTimeFromInterval()

QDateTime GKTSDescription::getTimeFromInterval

(

int

pos

)

const

Returns the time for a given interval position (based on from time and interval time)

getToTime()

const QDateTime & GKTSDescription::getToTime

(

)

const

getTypeName()

const QString & GKTSDescription::getTypeName

(

)

const

getUniqueName()

const QString & GKTSDescription::getUniqueName

(

)

const

hasNullValue()

bool GKTSDescription::hasNullValue

(

)

const

Returns true if a NULL value for this TS description has been set.

isMultidimensional()

bool GKTSDescription::isMultidimensional

(

)

const

Is the associated Time Series multidimensional?

isNull()

bool GKTSDescription::isNull

(

double

)

const

Returns true if "value" is a NULL (as defined with GKTSDescription::setNullValue).

resetMinMax()

void GKTSDescription::resetMinMax

(

)

Resets the maximum and minimum values

setAggregationType()

void GKTSDescription::setAggregationType

(

GK::AggregationType

type

)

When aggregating data, sets what is relevant: the mean or the sum.

setConversion()

void GKTSDescription::setConversion

(

const GK::Conversion

)

Units of this TS.

setExtraInfo()

void GKTSDescription::setExtraInfo

(

GKTimeSerie::ExtraInfo

avalue

)

Has deviation or bands for each value in the time series? Called automatically by the time series when a value with deviation or band is set.

setFromTime()

void GKTSDescription::setFromTime

(

const QDateTime &

)

setIntervalTime()

void GKTSDescription::setIntervalTime

(

const GKTimeDuration &

)

setToTimeKnow()

void GKTSDescription::setToTimeKnow
