Class SignedBinaryEncoder

java.lang.Object

org.apache.gora.accumulo.encoders.BinaryEncoder

org.apache.gora.accumulo.encoders.SignedBinaryEncoder

All Implemented Interfaces:

Encoder

public class SignedBinaryEncoder
extends BinaryEncoder

This class transforms this bits within a primitive type so that the bit representation sorts correctly lexographicaly. Primarily it does some simple transformations so that negative numbers sort before positive numbers, when compared lexographically.
