Number (Oracle Fusion Middleware Java API Reference for Oracle Generic Domains)

- oracle.jbo.domain.Number

All Implemented Interfaces:

java.io.Serializable, oracle.jbo.domain.DomainInterface, oracle.jbo.domain.KeyAttributeInterface
```
public class Number
extends java.lang.Object
implements oracle.jbo.domain.DomainInterface, java.io.Serializable, oracle.jbo.domain.KeyAttributeInterface
```
This class provides a lightweight wrapper for java.lang.Number, the native Java type for number objects. This wrapper allows an instance of the java.lang.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 java.lang.Number class such that it returns an instance of an oracle.jbo.domain.Number object.
Number objects consist of data (a byte array) and a Domain type code. Domain numbers extend SQL characters by being convertable to JDBC values.
