public class RowID
This class provides a lightweight wrapper for oracle.sql.RowID, the Java representation of the ROWID database type. This wrapper allows an instance of the oracle.sql.RowID to be used as an immutable Domain object.
RowID
objects consist of data (a byte array) and a Domain type code. Domain row IDs extend SQL row IDs by being convertable to JDBC values.
The oracle.jbo.domain.RowID 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.

Constructor Detail |

public RowID()
RowID
Domain object.
This constructor does not create a null RowID. To create a null RowID, use one of the NullValue
objects to indicate null.
public RowID(ROWID value)
Creates a RowID
Domain object from the given byte array.
value
- a value returned by a previous call to getBytes()
on an SQL object compatable with RowID
.public RowID(byte[] value)
Creates a RowID
Domain object from the given byte array.
value
- byte array containing the value of the RowID.public RowID(java.lang.String value)
Creates a RowID
Domain object from a Java String
.
value
- a textual representation of a RowID
.java.sql.SQLException
- if the representation is invalid.Method Detail |
---|
public static ORADataFactory getORADataFactory()
Initializes the RowID
Domain. This method is invoked when Business Components for Java is initialized.
ORADataFactory

Converts this RowID
Domain object back into an SQL ROWID
object.
