This module holds the core components of the Djenni data generator framework. By itself it provides most of the components to create an efficient end to end data generation framework for a specific domain. It contains the core SupplierBuilder interfaces, implementations for the core Java data types and useful test components. It is intended to be used in conjunction with the source-generator module that will speed up delivery of domain specific data generation and also with common domain modules (TBD) that deliver standard generators for common frameworks such as JAXB.

A visualization component for displaying a 3D scatter plot of the data using Java 3D. Requires Java 3D to be installed. This version adds built-in sampling controls to the GUI. The default sampling percentage is set so that a maximum of 5000 instances are plotted. The user can adjust this higher or lower to suit their available processing speed and memory.

High Performance Primitive Collections Realtime (fork of HPPC from Carrotsearch) Fundamental data structures (maps, sets, lists, queues, heaps, sorts) generated for combinations of object and primitive types to conserve JVM memory and speed up execution. The Realtime fork intends to extend the existing collections, by tweaking to remove any dynamic allocations at runtime, and to obtain low variance execution times whatever the input nature.

Dominate is the basement on which all other JavATE libraries are build. It contains interfaces for the basic patterns of domain driven design like "entity" and "repository". These interfaces gives you the possibility to access these objects in a standardized way allowing a lot of generalization and simplification. Side by side with these interfaces there are implementations that speed up the development of application using mainstream technologies like Hibernate, JPA, JCR and MongoDB.

Programmatically generate, load, modify, and convert Excel .xlsx spreadsheets in your Java applications. GrapeCity Documents for Excel (GcExcel) is a cross-platform high-speed, small-footprint spreadsheet API library that requires no dependencies on Excel. The powerful calculation engine supports 450+ Excel Functions and custom functions to perform complex calculations. GcExcel is 2x+ faster and uses less memory than Apache POI and allows you to save to XLSX, PDF, HTML, CSV, JSON and Images. Deploy your applications to the cloud, Windows, Mac, or Linux. If you'd like to remove the trial watermark and other trial limitations, please email [email protected] to request your 30-day evaluation key.

Voyager is a library for performing fast approximate nearest-neighbor searches on an in-memory collection of vectors. Voyager features bindings to both Python and Java, with feature parity and index compatibility between both languages. It uses the HNSW algorithm, based on the open-source hnswlib package, with numerous features added for convenience and speed. Voyager is used extensively in production at Spotify, and is queried hundreds of millions of times per day to power numerous user-facing features.

Java implementation of the Ziggurat algorithm for generating Gaussian distributed pseudorandom numbers. The Ziggurat algorithm is significantly faster than the more commonly encountered Polar method, and has some other desirable statistical properties. The ZigguratGaussian class is a Java port of the GNU Scientific Library's C implementation (Voss, 2005) of the Ziggurat method. In porting to Java, we have made several optimizations, the details of which can be found in the source code comments, which highlights any differences between this Java implementation and the C implementation on which it is based. This package also includes an implementation of the Polar Method, included to enable comparing speed advantage of the Ziggurat algorithm.

libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, AVX2, Neon, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, Arm, and PowerPC systems, as well as progressive JPEG compression on x86, x86-64, and Arm systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs.
