Class GeneralArray

public class GeneralArray extends AbstractSequence implements Array

A class to handle general multi-dimensional arrays. This class is unfinished. If the number of dimensions (the "rank") is one, should use a class that implements Sequence. GeneralArray uses a SimpleVector 'base' to store the actual data, and provides general linear mapping from the array indexes to an element index in the 'base' SimpleVector. Thus such uperations as transposing an array can be implement as just creating a simple re-mapping of the indexes.
