Interface DistanceFunction<TVector,​TDistance>

  • Type Parameters:
    TVector - Type of the vector to perform distance calculation on
    TDistance - Type of distance between items (expect any numeric type: float, double, int, ..)
    All Superinterfaces:
    Serializable
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
    @FunctionalInterface
public interface DistanceFunction<TVector,​TDistance>
extends Serializable
    Calculates distance between 2 items.
