oracle.jbo.domain
Class Date

java.lang.Object
  oracle.jbo.domain.Date

All Implemented Interfaces:

java.io.Serializable, oracle.jbo.domain.DomainInterface

public class Date
extends java.lang.Object
implements oracle.jbo.domain.DomainInterface, java.io.Serializable

This class provides a lightweight wrapper for java.sql.Date, the native Java type for date objects. This wrapper allows an instance of the java.sql.Date 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.sql.Date class such that it returns an instance of an oracle.jbo.domain.Date object.

JDevloper 3.1

boolean	equals(java.lang.Object other) Tests this for equality with another object.
java.lang.Object	getData()
long	getTime()
java.util.Date	getValue() Return a java.util.Date object with this domain's value.
int	hashCode() Computes a hash code for this.
void	setContext(oracle.jbo.domain.DomainOwnerInterface owner, oracle.jbo.Transaction trans, java.lang.Object ctx)
java.lang.String	toString() Converts this to a textual representation.

Method Detail

getTime

public long getTime()

getValue

public java.util.Date getValue()

Return a java.util.Date object with this domain's value. This method may be used to access the value for this domain in EL-expressions.

getData

public java.lang.Object getData()

Specified by:

getData in interface oracle.jbo.domain.DomainInterface
