java.lang.Object

edu.umn.cs.spatialHadoop.operations.KNN.TextWithDistance

All Implemented Interfaces:

TextSerializable, java.lang.Cloneable, java.lang.Comparable<KNN.TextWithDistance>

Enclosing class:

KNN

public static class KNN.TextWithDistance
extends java.lang.Object
implements java.lang.Cloneable, TextSerializable, java.lang.Comparable<KNN.TextWithDistance>

Stores a shape text along with its distance to the query point. Notice that it cannot be a ShapeWithDistance because we cannot easily deserialize it unless we know the right class of the shape.
