Type Members

  1. case class Ord[T](ex: Geometry, f: (T) ⇒ Geometry) extends Ordering[T] with Serializable with Product

Value Members

  1. def kNearest[G, H](rdd: RDD[G], centers: Traversable[H], k: Int)(g: (G) ⇒ Geometry, h: (H) ⇒ Geometry): Seq[Seq[G]]
  2. def kNearest[T](rdd: RDD[T], ex: Extent, k: Int)(f: (T) ⇒ Geometry): Seq[T]

    Determines the k-nearest neighbors of an RDD of objects which can be coerced into Extents.
