ipid-util

My common, open-source utilities. Support Java 8+.


What's included

Tupling: Tuple library

The project contains Tupling, a non-nullable, type-safe tuple library for Java. Though projects like commons-lang3, javatuples have already provided similar tuple libraries, they did not provide features like:

  • Support up to 26 tuples
    • Can't be more because there are too few letters in English
  • Null checking
  • Tuple concatenation
  • Public final field for elements
  • Shortened member accessing codes

When using javatuples, you'll have to write something like:

// p is a Pair<A, B>
p.getLeft().someOperation();

But with Tupling, all you need to do is simply:

p.a.someOperation();

Such feature shortens your code.

And since Optional is shipping since Java 8, there is no need for null in Java. Tupling provides null checking:

// Throws NullPointerException using Tupling
Tuple2.of(null, "123");

// Nothing throws with Apache Commons Lang or javatuples
Pair.with(null, "123");

Attention: The code is automatically generated. Modify those template files named *.jinja under /scripts/generate-tuple-code, if you want to make some changes.
