public class Timestamp

extends oracle.sql.TIMESTAMP

implements oracle.jbo.domain.DomainInterface, oracle.jbo.domain.XMLDomainWriter, oracle.jbo.domain.KeyAttributeInterface, oracle.sql.CustomDatum, java.io.Serializable

This class extends oracle.sql.TIMESTAMP, Oracle's Java representation of the TIMESTAMP database type. This class allows an instance of the oracle.sql.TIMESTAMP to be used as an immutable domain object.

The intent of many of the methods in this class is to wrap the corresponding method in the oracle.sql class such that it returns an instance of an oracle.jbo.domain.* object.

The oracle.jbo.domain.Timestamp 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.

Timestamp objects consist of data (a byte array) and a Domain type code. Domain dates extend SQL dates by being convertable to and from JDBC values.

Timestamp/Time Formats Accepted

The oracle.jbo.domain.Timestamp class accepts dates and times in the same format accepted by java.sql.TimeStamp (either a long milliseconds time value or the year, month, day, hour, minute, second, nano format) and java.sql.Timestamp (either a milliseconds time value or the year, month, day format).

Since:

JDeveloper 3.0

Constructor Detail

Timestamp

public Timestamp()

Creates a default Timestamp Domain object.

This constructor does not create a null date: use one of the NullValue() constructors.

Timestamp

public Timestamp(byte[] value)

Internal: Applications should not invoke this method.

Creates a Timestamp Domain object from the given byte array.

Parameters:

value - a value returned by a previous call to getBytes() on an SQL object compatable with Timestamp.

Timestamp

public Timestamp(Date value)

Timestamp

public Timestamp(oracle.sql.TIMESTAMP value)

Creates a Timestamp Domain object from an Oracle SQL TIMESTAMP.

Parameters:

value - a TIMESTAMP SQL object.

Timestamp

public Timestamp(Timestamp value)

Creates a Timestamp identical to an existing Timestamp.

Parameters:

value - a Timestamp Domain object.

Timestamp

public Timestamp(java.sql.Timestamp value)

Creates a Timestamp Domain object from a JDBC Timestamp.

Parameters:

value - a TIMESTAMP SQL object.

Timestamp

public Timestamp(long value)

Creates a Timestamp Domain object from a long Timestamp value. Uses java.sql.Timestamp(long) to create this domain instance. This value should usually be the value returned from System.currentTimeMillis() or from Timestamp.getTime() method

Timestamp

public Timestamp(java.sql.Date value)

Creates a Timestamp Domain object from a JDBC java.sql.Date object.

Parameters:

value - a Time SQL object.

Timestamp

public Timestamp(java.util.Date value)

Creates a Timestamp Domain object from a JDBC java.util.Date object.

Parameters:

value - a TimeStamp SQL object.

Timestamp

public Timestamp(java.lang.String value)

Creates a Timestamp Domain object from a Java String.

Parameters:

value - a textual representation of a Timestamp.

Method Detail

getCustomDatumFactory

public static oracle.sql.CustomDatumFactory getCustomDatumFactory()

Internal: Applications should not invoke this method.

Initializes the Timestamp Domain.

This method is invoked when JBO is initialized. Applications should not call this method directly.

Returns:

the CustomDatumFactory for the Timestamp Domain.

toDatum
