public class IntegerLexicoder
extends org.apache.accumulo.core.client.lexicoder.impl.AbstractLexicoder<Integer>
implements Lexicoder<Integer>

A lexicoder for signed integers. The encoding sorts Integer.MIN_VALUE first and Integer.MAX_VALUE last. The encoding sorts -2 before -1. It corresponds to the sort order of Integer.
