Specialized utility classes (which often collect static utility methods only) can be found in other places of ELKI as well, as seen below.

Important utility function collections:

• Util: Miscellaneous utility functions.
• OptionUtil: Managing parameter settings
• DatabaseUtil: database utility functions (centroid etc.).
• MathUtil: Mathematics utility functions.
• DistanceUtil: distance functions related (min, max for Distances).
• ResultUtil: result processing functions (e.g. extracting sub-results).
• ClassGenericsUtil: Generic classes (instantiation, arrays of arrays, sets that require safe but unchecked casts).
• LoggingUtil: simple logging.
• FormatUtil: output formatting.
• HTMLUtil: HTML (with XML DOM) generation.
• SVGUtil: SVG generation (XML DOM based).
• ByteArrayUtil: byte array processing (low-level IO via byte arrays)
• FileUtil: File and file name utility functions.
