java.lang.Object oracle.jbo.server.RowImpl oracle.jbo.server.ViewRowImpl
public class ViewRowImpl
A View Object Row. This class provides access to a View Object Row. The View Object Row can contain one or more Entity Object Rows in addition to derived attributes such as calculated columns.
The Business Components for Java framework instantiates an object of this class for each record that is returned by the row's View Object query. This class can be referred to by middle-tier customer application logic in order to access View Object Row data.
Customers can extend this class with custom View Object Row implementations. For example, the Business Components for Java View Object wizard can be used to generate sub-classes of this class that define type-safe accessors/mutators for the attributes of a row. Custom sub-classes should be declard to the Business Components for Java framework through the View Object wizard.
Customer applications should not access this class on the client-tier of an
application. Instead, the Row
interface should be
used for client tier access.

This method invokes create(AttributeList)
on each of the "new" entities
that make up this View Row.
The attribute list nvp is simply passed to the new entity rows that make up this View Row.
Note: the names in the attribute list are not transformed into entity-relative names hoping that the caller has done so already. If not, the entity's create() method might fail.

protected void setEntities(EntityImpl[] rows)
This method is called by framework, after entites are created for this row. This must be protected because subclasses can create their own entity instances and have the viewrow manage them.
For example, assume there is a ViewRow on the Doc Entity where Doc has subclasses PO and Req, the ViewRow subclass can create PO/Req instances of entities based on some logic and have ViewRow manage them as an entity of type Doc.

A view row is based on entity rows. This method can be used
to set the entity row for the specified entity index. For
example, a view row may consist of two entity rows, Emp
and Dept. To set the entity row for the Dept part, one
can call this method with index
of 1.

Populate this row from the ResultSet.
This is a Framework-internal method. This method is used to fill in entity-attributes from a JDBC ResultSet that is returned by executeQuery().
Note that the method works on the current row of the result set and any currecy change on the ResultSet could throw it off. This method is protected to let sub-ViewRows fill in custom-entities created based on data.
For example, if fax is a subtype of doc and based on a column value, either doc is created or a fax is created for a given entity type, this method may be used to create entities based on the data values. Note that the developer needs to know exact position of values in the JDBC ResultSet.
