Interface OBInt

All Superinterfaces:

OB, Storable

All Known Implementing Classes:

OBVectorInt

public interface OBInt
extends OB

Any Object whose distance function returns ints must implement this interface. WARNING: The equals method *must* be implemented. The equals does not have to be true when the distance returns 0. Note however that at search time, elements of distance 0 are treated in the same way. Equals is only used when the database is queried for the existence of an object.
