java.lang.Object oracle.jbo.domain.Array
public class Array
This class provides a lightweight wrapper for oracle.sql.ARRAY, the Java representation of the ARRAY database type. This wrapper allows an instance of the oracle.sql.ARRAY to be used as an immutable Domain object. This class also provides a wrapper for the data that comes from nested tables and nested arrays.
