java.lang.Object
  de.lmu.ifi.dbs.elki.utilities.IntegerTriple

All Implemented Interfaces:

Comparable<IntegerTriple>

public class IntegerTriple
extends Object
implements Comparable<IntegerTriple>

Provides a key of three integers. Two IntegerTriple-Objects are equal, if they consist of the same three integers defined in the same order.

Constructor Detail

IntegerTriple

public IntegerTriple(int first,
                     int second,
                     int last)

Constructor which initiates an IntegerTriple Object with three integers.

Parameters:

first - first integer-value

second - second integer-value

last - third integer-value

IntegerTriple

public IntegerTriple()

Empty constructor creating an IntegerTriple-Object.

Method Detail

getFirst

public int getFirst()

Returns:

the first integer-value of the IntegerTriple-Object.

getSecond

public int getSecond()

Returns:

the second integer-value of the IntegerTriple-Object.

getLast

public int getLast()

Returns:

the third integer-value of the IntegerTriple-Object.

compareTo

public int compareTo(IntegerTriple o)

Compares this IntegerTriple with an IntegerTriple o. If this Object is greater than the other object, then 1 is returned, else if the two Objects are equal, 0 is returned. If IntegerTriple o is greater then this IntegerTriple, then -1 is returned.

Specified by:

compareTo in interface Comparable<IntegerTriple>

hashCode

public int hashCode()

Creates the hashCode dependent on the three integers this Object consist.

Overrides:

hashCode in class Object

Returns:

the hashCode of this Object

equals

public boolean equals(Object obj)

Verifies if this Object is equals to Object obj.

Overrides:

equals in class Object

Parameters:

obj - object to be compared with this object

Returns:

true if this Object is equals to Object obj, false otherwise

setFirst

public void setFirst(int first)

Sets the first Argument of this Object.

Parameters:

first -

setSecond

public void setSecond(int second)

Sets the second Argument of this Object.

Parameters:

second -

setLast

public void setLast(int last)

Sets the third Argument of this Object.

Parameters:

last -
