Description

This library provides an implementation for the four basic unsigned integer types as wrappers:

• UByte
• UShort
• UInteger
• ULong

These classes extend java.lang.Number and implement java.lang.Comparable<?>, just like the JDK's own wrapper types. Besides, there is a utility class called org.joou.Unsigned with factory methods allowing for creating unsigned wrappers like this:

import static org.joou.Unsigned.*;

// and then...
UByte    b = ubyte(1);
UShort   s = ushort(1);
UInteger i = uint(1);
ULong    l = ulong(1);

This project was created for https://www.jooq.org, to provide better support for MySQL, Postgres, and other databases' unsigned integer data types, and has been open sourced as an independent library for usage outside of jOOQ.
