All Implemented Interfaces:

Array, Cloneable

Direct Known Subclasses:

DenseSNDArray

public abstract class DenseNumberArray

extends AbstractArray

An Array wrapper for an array of Numbers. Differs from DenseDoubleArray in that it stores the Numbers rather than the primitive doubles Helpful when one needs to store BigDecimals or ScientificNotationDoubles Does not define set(int i, int val) or set(int i, double val); the subclasses, such as DenseScientificNotationDoubleArray should define these methods
