oracle.jbo.common.SparseArrayImpl
public class SparseArrayImpl
The SparseArrayImpl represents Data from the datastore along with a flag whether data exists in a particular index into the array or not. This Array is designed for arrays that have small numbers of elements with a medium (200-400) spread on the indices. This array doesn't shrink the storage as tail-elements are removed because it assumes that the spread isn't very large.
Only ready only access is allowed to data within this class-instance.
