      wt.pds.PersistableViewItemBuilder

All Implemented Interfaces:

Externalizable, ItemBuilder, Serializable

public class PersistableViewItemBuilder

extends PersistableItemBuilder

implements Externalizable

This class provides the functionality for building a "full" Persistable object from a result set. All of the attributes in the object are included in the result set. The Persistable that is returned is specified by the view class attribute. Sub-classes that are queried return only the columns from the view class and instances are of the view class type.

Supported API: false

Extendable: false
