AlgART Libraries is a collection of Java libraries for processing arrays and matrices. It features63-bit addressing of array elements (64-bit long int indexes), a memory model concept (allowing data to be stored using different schemes, from RAM to mapped disk files), wide usage of lazy evaluations, built-in multithreading optimization for multi-core processors, and a wide set of image processing algorithms over matrices. Almost all classes and methods are thoroughly documented via JavaDoc.
Funcito is a Java library which simplifies access to your favorite functional programming APIs by wrapping Java methods as the function-type objects defined in those libraries. Rather than creating another functional programming API, Funcito makes it easy to define function-type objects which wrap existing methods. As a result, your code has less noise and clutter of anonymous inner classes, annotations, etc. Your code remains safe for automated refactoring, since there are no String-based reflection or forced naming conventions. The supported frameworks are Google Guava, Jedi, Functional Java, Play! Framework 2, collections-generic, and Netflix RxJava.
