Constructor Detail

NormalisedBinnedData

public NormalisedBinnedData(BinnedData base)

Constructor.

Parameters:

base - binned data object providing basic functionality

Method Detail

submitDatum

public void submitDatum(double value,
                        double weight,
                        boolean[] setFlags)

Description copied from interface: BinnedData

Submits a value for inclusion in this BinnedData object. As well as the value itself and a weight, a mask of boolean flags is given that indicates which subsets are considered to contain the submitted value.

Specified by:

submitDatum in interface BinnedData

Parameters:

value - value for inclusion

weight - weighting

setFlags - array of flags, one for each subset; true for inclusion, false for exclusion

getSetCount

public int getSetCount()

Description copied from interface: BinnedData

Returns the number of subsets for which this object maintains bins.

Specified by:

getSetCount in interface BinnedData

Returns:

set count

isInteger

public boolean isInteger()

Returns false.

Specified by:

isInteger in interface BinnedData

Returns:

true if all Bin.getWeightedCount returns are integer values

getBinIterator

public Iterator getBinIterator(boolean includeEmpty)

Description copied from interface: BinnedData

Returns an iterator over the bins managed by this object. The bins must be returned in order (lowest data range bin to highest data range bin).

It is inadvisable to call BinnedData.submitDatum(double, double, boolean[]) during the lifetime of this iterator.

Specified by:

getBinIterator in interface BinnedData

Parameters:

includeEmpty - if true, then all bins between the lowest and highest must be iterated over. If false, then empty bins may be omitted

Returns:

iterator which dispenses BinnedData.Bin instances
