Class IntIntPair

java.lang.Object

de.lmu.ifi.dbs.elki.utilities.pairs.IntIntPair

All Implemented Interfaces:

PairInterface<Integer,Integer>, Comparable<IntIntPair>

public class IntIntPair
extends Object
implements Comparable<IntIntPair>, PairInterface<Integer,Integer>

Pair storing two integers. Since int is a native type, this can't be done via the CPair generic.

Constructor Detail

IntIntPair

public IntIntPair(int first,
          int second)

Constructor

Parameters:

first - First value

second - Second value

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(IntIntPair other)

Implementation of comparable interface, sorting by first then second.

Specified by:

compareTo in interface Comparable<IntIntPair>

Parameters:

other - Object to compare to

Returns:

comparison result

compareSwappedTo

public int compareSwappedTo(IntIntPair 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,Integer>

Returns:

First object

setFirst

public final void setFirst(int first)

Set first value

Parameters:

first - new value

getSecond

@Deprecated
public final Integer 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,Integer>

Returns:

Second object

setSecond

public final void setSecond(int second)

Set second value

Parameters:

second - new value
