Class SparseArray

java.lang.Object

oracle.jbo.common.SparseArrayImpl

oracle.jbo.server.SparseArray

All Implemented Interfaces:

java.io.Serializable, SparseArrayInterface

public class SparseArray
extends SparseArrayImpl
implements SparseArrayInterface

The SparseArray 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.
