Constructor Detail

GenericDistanceResultPair

public GenericDistanceResultPair(D first,
                                 DBID second)

Canonical constructor

Parameters:

first - Distance

second - Object ID

Method Detail

getDistance

public final D getDistance()

Getter for first

Specified by:

getDistance in interface DistanceResultPair<D extends Distance<D>>

Returns:

first element in pair

setDistance

public final void setDistance(D first)

Setter for first

Specified by:

setDistance in interface DistanceResultPair<D extends Distance<D>>

Parameters:

first - new value for first element

getDBID

public final DBID getDBID()

Getter for second element in pair

Specified by:

getDBID in interface DistanceResultPair<D extends Distance<D>>

Returns:

second element in pair

setID

public final void setID(DBID second)

Setter for second

Specified by:

setID in interface DistanceResultPair<D extends Distance<D>>

Parameters:

second - new value for second element

compareByDistance

public int compareByDistance(DistanceResultPair<D> o)

Description copied from interface: DistanceResultPair

Compare value, but by distance only.

Specified by:

compareByDistance in interface DistanceResultPair<D extends Distance<D>>

Parameters:

o - Other object

Returns:

comparison result, as by Double.compare(this, other)

compareTo

public int compareTo(DistanceResultPair<D> o)

Specified by:

compareTo in interface Comparable<DistanceResultPair<D extends Distance<D>>>

equals

public boolean equals(Object obj)

Description copied from class: Pair

Simple equals statement. This Pair equals another Object if they are identical or if the other Object is also a Pair and the Pair.first and Pair.second element of this Pair equal the Pair.first and Pair.second element, respectively, of the other Pair.

Overrides:

equals in class Pair<D extends Distance<D>,DBID>

Parameters:

obj - Object to compare to

toString

public String toString()

Description copied from class: Pair

Canonical toString operator

Overrides:

toString in class Pair<D extends Distance<D>,DBID>
