Constructor Detail

EpsilonRange_ListElement

public EpsilonRange_ListElement(double distance,
                                DataObject dataObject)

Constructs a new Element that is stored in the ArrayList which is built in the k_nextNeighbourQuery-method from a specified database. This structure is chosen to deliver not only the DataObjects that are within the epsilon-range but also deliver the distances that were calculated. This reduces the amount of distance-calculations within some data-mining-algorithms.

Parameters:

distance - The calculated distance for this dataObject

dataObject - A dataObject that is within the epsilon-range

Method Detail

getDistance

public double getDistance()

Returns the distance that was calulcated for this dataObject (The distance between this dataObject and the dataObject for which an epsilon-range-query was performed.)

Returns:

distance

getDataObject

public DataObject getDataObject()

Returns this dataObject

Returns:

dataObject

getRevision

public java.lang.String getRevision()

Returns the revision string.

Specified by:

getRevision in interface RevisionHandler

Returns:

the revision
