Constructor Detail

ScalarImpl

public ScalarImpl(MetElement element,
                  Interval dateRange,
                  SummaryHistory composition,
                  double measurementHeight,
                  String label)

Creates a scalar sequence.

Parameters:

dateRange - the interval for which values are stored

composition - a record of how raw data has been summarised to make the sequence.

measurementHeight - the height in metres;

ScalarImpl

public ScalarImpl(MetElement element,
                  Interval dateRange,
                  SummaryHistory composition,
                  String label)

Creates a scalar sequence. This constructor uses the default height for temperature measurements.

Parameters:

dateRange - the interval for which values are stored

composition - a record of how raw data has been summarised to make the sequence.

Method Detail

putInstantValue

public void putInstantValue(Date time,
                            float value)

Records the instantaneous value at a particular time

Parameters:

time - the point in time

value - the value at that time

Throws:

IllegalArgumentException - if the time is outside the interval that the period is intended to store

putValueOverInterval

public void putValueOverInterval(Interval interval,
                                 float value)

Records the average value over some subinterval.

Parameters:

interval - the period of time over which the measurement was taken.

value - the average value over that interval

Throws:

IllegalArgumentException - if the subinterval is outside the interval that the sequence was constructed to store

getMinimum

public JigsawQuantity getMinimum(Interval interval)

Returns the minimum value over the interval. Temperatures at either end of the interval are included in the comparison if more than 50% of their duration lies within the interval of interest.

Returns:

the minimum value

getMaximum

public JigsawQuantity getMaximum(Interval interval)

Returns the maximum value over the interval. Sequence values at either end of the interval are included in the comparison if more than 50% of their duration lies within the interval of interest.

Returns:

the maximum value

getInstant

public JigsawQuantity getInstant(Date time)

Returns the instantaneous value at a particular point in time. If interpolation is requested, the value may be spatially and/or temporally interpolated from other data.

Returns:

the instantaneous value

getAverage

public JigsawQuantity getAverage(Interval interval)

Returns the average temperature over the interval. Temperatures at either end of the interval are included by weighting their values according to the proportion of their duration that lies in the period of interest.

Returns:

the average value

getContentsAsString

public String getContentsAsString(Date time,
                                  String delimiter)

Description copied from interface: Sequence

Returns the measurement associated with a particular time as a string. Used by dumpSequence.

Specified by:

getContentsAsString in interface Sequence

Specified by:

getContentsAsString in class GeneralSequenceImpl

getMeasurementHeight

public double getMeasurementHeight()

getNumberOfSubComponents

public int getNumberOfSubComponents()

Description copied from interface: Sequence

Get the number of sub-components in the sequence. This indicates how many "columns" the sequence output will occupy.

Specified by:

getNumberOfSubComponents in interface Sequence

Specified by:

getNumberOfSubComponents in class GeneralMetSequenceImpl

getSubHeading

public String getSubHeading(int index)

Returns the subheading by looking up the corresponding key in WeatherDataResources

Specified by:

getSubHeading in interface CompoundSequence

Specified by:

getSubHeading in class GeneralMetSequenceImpl

setSubHeading

public void setSubHeading(int index,
                          String aHeading)

Does nothing

Specified by:

setSubHeading in interface CompoundSequence

Specified by:

setSubHeading in class GeneralMetSequenceImpl

getData

public double[] getData(int index)

Description copied from interface: CompoundSequence

Creates a one-dimensional array containing one subcomponent of the data. Use CompoundSequence.getCoverage(int) to test for missing values (at present these are returned as Double.NaN but don't rely on this).
Note that the first element of the array corresponds to getStart() and is therefore empty in most cases.

Specified by:

getData in interface CompoundSequence

Specified by:

getData in class GeneralSequenceImpl

getCoverage

public float[] getCoverage(int index)

Description copied from interface: CompoundSequence

Indicates which array elements returned by CompoundSequence.getData(int) are missing. Coverage values are in the range JigsawQuantity.DEVOID to JigsawQuantity.COMPLETE.
Note that the first element of the array corresponds to getStart() and is therefore empty in most cases.

Specified by:

getCoverage in interface CompoundSequence

Specified by:

getCoverage in class GeneralSequenceImpl

clone

public Object clone()

Specified by:

clone in interface Sequence

Overrides:

clone in class GeneralSequenceImpl
