Class DoubleArrayStaticHistogram

java.lang.Object

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.AbstractStaticHistogram

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.AbstractObjStaticHistogram<double[]>

de.lmu.ifi.dbs.elki.utilities.datastructures.histogram.DoubleArrayStaticHistogram

All Implemented Interfaces:

Histogram, ObjHistogram<double[]>

public final class DoubleArrayStaticHistogram
extends AbstractObjStaticHistogram<double[]>

Histogram containing an array of doubles (i.e. double[]). This is actually one of the simpler specializations, as arrays are objects not primitive in Java.

Constructor Detail

DoubleArrayStaticHistogram

public DoubleArrayStaticHistogram(int bins,
                          double min,
                          double max,
                          int cols)

Constructor.

Parameters:

bins - Number of bins

min - Minimum value for the coordinates

max - Maximum value for the coordinates

cols - Number of columns in each bin.

Method Detail

increment

public void increment(double coord,
             double[] data)

Increment histogram by a double[].

Parameters:

coord - Coordinate

data - Data to increment by.

putData

@Deprecated
public void putData(double coord,
                      double[] data)

Deprecated. use the explicit increment(double, double[]) instead.

Aggregate new data into the histogram. Note that the actual definition of "aggregate" depends on the application. While a static histogram will likely perform this immediately, a flexible histogram will cache a number of observations. Data is combined by incrementing.

Parameters:

coord - Coordinate

data - Data

makeObject

protected double[] makeObject()

Description copied from class: AbstractObjStaticHistogram

Class to make a new object for the data store.

Specified by:

makeObject in class AbstractObjStaticHistogram<double[]>

Returns:

New instance.
