Library with some useful things for my Scala needs

Simply download the file scala_utils.jar in the out folder, or click here.

• util - main package, contains various useful classes and objects
  • Odds [mutable] - implementation of Pondered with a fetching method that uses RNG as ponderation
  • Pondered [mutable] - trait that contains a Seq of tuples (element, ponderation) that can be fetched according to a certain ponderation rule
  • Random - static object version of the scala.util.Random class
  • Sequence [mutable] - class describing a simple mathematical sequence with an initial value and a function that is applied everytime next or skip is called
  • collection - contains immutable collection classes
    • Ring [immutable] - class describing a zipper-list-like structure with both ends linked together
    • Zipper [immutable] - class describing an immutable list that you can browse forwards or backwards. [to be extended into a tree version]
  • exception - contains custom exceptions
    • EmptyRingException - thrown when trying to create a Ring with no values inside
    • EndOfZipperException - (unused yet) thrown when trying to read past the end points of a zipper
    • BadCoordSystemException - thrown when trying to create a CoordSystem with parallel or null vectors
  • geometry - contains basic classes for geometry
    • CoordSystem [immutable] - class describing a cartesian coordinate system for the plane
    • BaseCoordSystem [immutable] - object describing the default coordinate system, origin (0, 0) and vectors (1, 0) and (0, 1)
    • Point [immutable] - point on the plane, described relatively to a coordinate system (base system by default)
    • Vector [immutable] - vector on the plane, described relatively to a coordinate system (base system by default)
  • tool - contains various, more specific functions
    • DeclineZipper - very specific function that returns a list of all possible zipper states from a list passed as an argument
    • IO - functions for reading and using files
    • Shuffle - very simple function that shuffles a list of arguments (O(n))
