OBVectorShort

public OBVectorShort(Random r,
                     int dim)

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

Method Detail

equals

public boolean equals(Object o)

Overrides:

equals in class Object

distance

public short distance(OBShort object)
               throws OBException

Description copied from interface: OBShort

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

Specified by:

distance in interface OBShort

Parameters:

object - The object of type OBShort 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
