org.apache.accumulo.core.client.lexicoder.UIntegerLexicoder

All Implemented Interfaces:

Encoder<Integer>, Lexicoder<Integer>, org.apache.accumulo.core.iterators.TypedValueCombiner.Encoder<Integer>

public class UIntegerLexicoder
extends Object
implements Lexicoder<Integer>

A lexicoder for an unsigned integer. It sorts 0 before -1 and does not preserve the native sort order of a Java integer because Java does not contain an unsigned integer. If Java had an unsigned integer type, this would correspond to its sort order.
