Constructor Summary

OBVectorInt()
Default constructor must be provided by every object that implements the interface OB.

OBVectorInt(int[] data)

OBVectorInt(Random r, int dim)
Creates a new vector with dim dimensions created by Random.nextInt()

Method Summary

int	distance(OBInt object) Calculates the similarity of "this" and "object".
boolean	equals(Object o)
void	load(byte[] input) Populates the object's internal properties from the given byte stream.
byte[]	store() Stores this object in a byte array.

OBVectorInt

public OBVectorInt(Random r,
                   int dim)

Creates a new vector with dim dimensions created by Random.nextInt()

Method Detail

equals

public boolean equals(Object o)

Overrides:

equals in class Object

distance

public int distance(OBInt object)
             throws OBException

Description copied from interface: OBInt

Calculates the similarity of "this" and "object". The function must satisfy the triangular inequality and return a int.

Specified by:

distance in interface OBInt

Parameters:

object - The object of type OBInt to be compared

Throws:

OBException - User generated exception

load

public void load(byte[] input)
          throws OBException,
                 IOException

Description copied from interface: Storable

Populates the object's internal properties from the given byte stream.

Specified by:

load in interface Storable

Parameters:

input - byte array from where we will load data.

Throws:

OBException - if the data cannot be loaded.

IOException

store

public byte[] store()
             throws OBException,
                    IOException

Description copied from interface: Storable

Stores this object in a byte array.

Specified by:

store in interface Storable

Throws:

OBException

IOException
