GUJO - Gary's Unsigned Java Objects

Author: Gary Hammock, PE

#Description

This package seeks to implement the unsigned objects that were (in the author's opinion) wrongly excluded from the Java language. Unsigned bytes and words are indispensable when trying to implement cryptographic functions. Since Java doesn't include these as primitives, the GUJO package attempts to provide this functionality.

The objects are extensions of the java.lang.Number class and implements the Comparable interface so the classes can be used in sortable lists.

As an extension of java.lang.Number, the class definitions must include a serialVersionUID. The generated UID for each class is as follows:

#Implementation

Unsigned bytes:

UByte myByte = new UByte();
myByte.assign(0x42);

UByte anotherByte = new UByte(0x20);

Unsigned 32-bit integers:

UInt myInt = new UInt();
myInt.assign(123456);

UInt anotherInt = new UInt(1337);

#Future Work Implementing 64-bit long integers and 16-bit short integers.
