oracle.jbo.server.RowImpl
public abstract class RowImpl
Base class for Entity Rows and View Object Rows. This class defines common methods for Entity Row and View Object Row access. Customer application logic can use this class to access database table rows independently of the implementation of the underlying row. For example, assume that a customer application is written to perform batch style inserts into a database table. This application may reference the RowImpl class for row access instead of accessing instances of ViewRowImpl or EntityImpl directly. This design would allow changes in a row's implementation (Entity Row or View Object Row) without necessitating changes in the application logic.
Unlike the Row
interface which provides tier-independent access to database table rows, this class can only be referenced by logic that executes on an application's middle tier.
Customers should not develop implementations of this abstract class. Instead, customers who need to extend/override Row behavior should extend one of the concrete Row classes: EntityImpl
and ViewRowImpl
.

Use this method whenever data is required in XML format, either to present a UI (after converting XML data into some HTTP format using a stylesheet) or to pass the data as payload for messages via JMS.
The options parameter represents a set of bit flags that will control the writeXML behavior. The following bit flags have been defined:

Row
This method should be used to create a row and then to mark it temporary (STATUS_INITIALIZED) so that an app can use the created Row to fill UIs like Table UIs with valid default values for rows. Then when the Row values are updated, UIs should once again call this method to turn the Row into new (STATUS_NEW) state before any setAttribute calls on the Row, so that the changes are validated and posted.
When a created row is in STATUS_NEW (by default) state and this method is called to turn the row in to STATUS_INITIALIZED, all updateable entities that this row comprises of, de=registers themselves from their respective transaction and validation managers. Assocation and ViewLink finders will not find/include these rows. Only the collection into which this row was inserted into will contain a reference to this row and when that collection is re-executed this row cannot be reached via the framework. To include this row again an app should call this method again with STATUS_NEW as the method-argument
When this row is in STATUS_INITIALIZED state and this method is called with STATUS_NEW state then, this new row is added back into it's relevant transaction and validation manager and will then participate in validation, transaction cycles.
Note that incase of composition if a master/detail hierarchy is being created with the intention of making them temporary (STATUS_INITIALIZED) then the logic should be: Create Master row, insert Master row into a collection, create Detail row insert detail row into a relevant collection, make detail row initialized, create/insert/change-to-initialized more detail rows and at the end set the master row as initialized.
