jooq/joou

jOOU - Unsigned Integers jOOU provides unsigned integer versions for the four Java integer types byte, short, int and long.

joou's Issues

Modularise jOOU and cross-release a Java 6 and Java 9 deliverable

Similar to jOOQ, jOOR, and jOOX we should cross-release jOOU in order to be able to deliver it as a Java 9 module.

Since we're currently not doing anything specific to Java 8, a Java 8 deliverable is not necessary. We can still add such an artifact later on, if we're adding anything specific to Java 8

Missing exports section in module-info.java

The current modularisation does not export any packages, making the module useless.

UInteger range inconsistencies

Unsigned integer range handling has incorrectnesses / inconsistencies.

E.g. UInteger can be formed from integer -34 but not from long -34.

@Test
public void test_negative_uint_34il() {
    UInteger a = uint(-34);
    UInteger b = uint(-34L);
    assertTrue (a == b);
}

Reported error is Exception in thread "main" java.lang.NumberFormatException: Value is out of range : -34 for the b definition.

I would either expect both of the samples below to fail or succeed, but not act differently. What is the intent in this library? Shouldn't both these cases succeed, since -34 is a value that is representable in 32 bit signed integer?

Make the library an OSGi Bundle

Improve { UShort | UInteger }.toBigInteger()

This change from jOOQ should be merged back to jOOU:

glm/UMath better support

Hi,

first of all, let me say it is a really cool project!

Second, we are working on a java glm here and at the moment I am implementing all the unsigned types, Vec2ub, Vec2ui, and so on

I am really interested in jOOU and I was wondering if it'd be possible to facilitate my task by implementing additional methods such as min(uX, uY), max(uX, uY) in a, let's say, UMath class...

For info, I am currently implementing such a class, but it'd be cool I could move it inside jOOU :)

Storing UByte[] in mysql

Expected behavior and actual behavior:

I get an error saying: Incorrect string value: '\x00\x00...' for column ...

Steps to reproduce the problem:

Create a JPA entity with a field of type UByte[] and persist it

Versions:

• jOOU:
  joou-java-6 / 0.9.3
• Java:
  openJdk 8

Improved hashCode() and toString() implementation

The current implementation on e.g. UByte.toString() is:

    @Override
    public String toString() {
        return Short.valueOf(value).toString();
    }

This produces an unnecessary allocation of a java.lang.Short, when instead, we could write

    @Override
    public String toString() {
        return Short.toString(value);
    }

Other types are also affected.

Add bitwise operations

Versions:

• jOOU latest
• Java 8

Add bitwise operations

Can we add bitwise operations to the library?

See my question for motivation:
https://stackoverflow.com/questions/68991707/how-to-do-unsigned-integer-bit-operations-in-java-1-8-that-match-ones-in-c

So just like we have the add and subtract operators, add:

and
or
xor
compliment
leftShift
rightShift
rightShiftZeroFill

I added the library using "Library dependencies" and i searched for jOOU, it added the following line into my gradle file :

compile 'org.jooq:joou:0.9.1'

Replace <source> and <target> by <release> in pom.xml

Since we're now building with JDK 9+, we should use the new <release> flag rather than <source> and <target>. It also sets the -bootclasspath compiler option. See: https://stackoverflow.com/q/43102787/521799

Add a byte array output

The main advantage, for me, to have unsigned primitives, is to permit a byte array output of the unsigned number.

Add ULong.add(long) and subtract(long)
