Class IntDoublePair

java.lang.Object
  de.lmu.ifi.dbs.elki.utilities.pairs.IntDoublePair

All Implemented Interfaces:

PairInterface<Integer,Double>, Comparable<IntDoublePair>

public class IntDoublePair
extends Object
implements Comparable<IntDoublePair>, PairInterface<Integer,Double>

Pair storing an integer and a double. Since double and int are native types, this can't be done via the CPair generic.

Field Summary

static Comparator<IntDoublePair>	BYFIRST_COMPARATOR Comparator to compare by second component only
static Comparator<IntDoublePair>	BYSECOND_COMPARATOR Comparator to compare by second component only
int	first first value
double	second second value
static Comparator<IntDoublePair>	SWAPPED_COMPARATOR Comparator to compare by swapped components

Constructor Summary

IntDoublePair(int first, double second)
Constructor

Method Summary

int	compareSwappedTo(IntDoublePair other) Implementation of comparableSwapped interface, sorting by second then first.
int	compareTo(IntDoublePair other) Implementation of comparable interface, sorting by first then second.
boolean	equals(Object obj) Trivial equals implementation
Integer	getFirst() Deprecated. use pair.first to avoid boxing!
Double	getSecond() Deprecated. use pair.first to avoid boxing!
int	hashCode() Trivial hashCode implementation mixing the two integers.
void	setFirst(int first) Set first value
void	setSecond(double second) Set second value
String	toString() Returns first and second value.

Constructor Detail

IntDoublePair

public IntDoublePair(int first,
                     double second)

Constructor

Parameters:

Method Detail

equals

public boolean equals(Object obj)

Trivial equals implementation

Overrides:

equals in class Object

Parameters:

obj - Object to compare to

hashCode

public final int hashCode()

Trivial hashCode implementation mixing the two integers.

Overrides:

hashCode in class Object

compareTo

public int compareTo(IntDoublePair other)

Implementation of comparable interface, sorting by first then second.

Specified by:

compareTo in interface Comparable<IntDoublePair>

Parameters:

other - Object to compare to

Returns:

comparison result

compareSwappedTo

public int compareSwappedTo(IntDoublePair other)

Implementation of comparableSwapped interface, sorting by second then first.

Parameters:

other - Object to compare to

Returns:

comparison result

getFirst

@Deprecated
public final Integer getFirst()

Deprecated. use pair.first to avoid boxing!

Description copied from interface: PairInterface

Get the first object - note: this may cause autoboxing, use pair.first for native pairs!

Specified by:

getFirst in interface PairInterface<Integer,Double>

Returns:

First object

setFirst

public final void setFirst(int first)

Set first value

Parameters:

first - new value

getSecond

@Deprecated
public final Double getSecond()

Deprecated. use pair.first to avoid boxing!

Description copied from interface: PairInterface

Get the second object - note: this may cause autoboxing, use pair.second for native pairs!

Specified by:

getSecond in interface PairInterface<Integer,Double>

Returns:

Second object

setSecond

public final void setSecond(double second)

Set second value

Parameters:

second - new value

toString

public String toString()

Returns first and second value.

Overrides:

toString in class Object
