oracle.sql.NUMBER
oracle.jbo.domain.Number
public class Number
This class extends oracle.sql.NUMBER, Oracle's Java representation of the NUMBER database type. This class allows an instance of the oracle.sql.NUMBER to be used as a domain object. The intent of many of the methods in this class is to wrap the corresponding method in the oracle.sql.NUMBER class such that it returns an instance of an oracle.jbo.domain.Number object.
The oracle.jbo.domain.Number domain class is the Java representation of the underlying database type that you must use if you want to exploit the domain feature of Business Components for Java.
