Class ShortLexicoder

java.lang.Object

org.locationtech.geowave.core.index.lexicoder.ShortLexicoder

All Implemented Interfaces:

NumberLexicoder<Short>

public class ShortLexicoder
extends Object
implements NumberLexicoder<Short>

A lexicoder for signed integers (in the range from Short.MIN_VALUE to Short.MAX_VALUE). Does an exclusive or on the most significant bit to invert the sign, so that lexicographic ordering of the byte arrays matches the natural order of the numbers.
