Constructor Detail

OBVectorByte

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


OBVectorByte

public OBVectorByte(byte[] data)

OBVectorByte

public OBVectorByte(Random r,
                    int dim)
Creates a new vector with dim dimensions created by Random.nextByte()

Method Detail

equals

public boolean equals(Object o)
Overrides:
equals in class Object

distance

public byte distance(OBByte object)
              throws OBException
Description copied from interface: OBByte
Calculates the similarity of "this" and "object". The function must satisfy the triangular inequality and return a byte.

Specified by:
distance in interface OBByte
Parameters:
object - The object of type OBByte 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
