Class OBResultInvertedByte<O>

java.lang.Object
  net.obsearch.AbstractOBResult<O>
      net.obsearch.result.OBResultInvertedByte<O>

All Implemented Interfaces:

Comparable

public final class OBResultInvertedByte<O>
extends AbstractOBResult<O>

This class is used to store a single match result. A single result consists of the object found, the distance of this object with the query and an internal id. Inverted results will put first smaller values in the priority queue.

Since:

0.7

Distance of the object found and the query.

Constructor Detail

OBResultInvertedByte

public OBResultInvertedByte()

Default constructor. Used mostly to minimize the amount of object creations.

OBResultInvertedByte

public OBResultInvertedByte(O object,
                            long id,
                            byte distance)

Create a new OBResultByte.

Parameters:

object - the result found.

id - The internal id of the result.

distance - Distance of the result and the original query.

Method Detail

getDistance

public final byte getDistance()

Returns:

The distance of the result and the original query.

setDistance

public final void setDistance(byte x)

Sets the distance to a new value x.

Parameters:

x - The new value to set.

compareTo

public int compareTo(Object o)

We implement the interface comparable so we provide this method. The only difference is that we return bigger objects first. (The comparable contract is multiplied by -1)

Parameters:

o - The object that will be compared.

Returns:

1 if this object is smaller than o 0 if this object is equal than o -1 if this object is greater than o

toString

public String toString()

Return a human readable representation of the object.

Overrides:

toString in class Object

Returns:

a human readable representation of the object.
