public class ViewLinkImpl
Implements the
ViewLink
interface, the middle-tier class that manages
a master-detail relationship between two View Objects.
A View Link models the master-detail relationship between two View Objects. The actual relationship is implemented between a row set iterator derived from the master View Object, and a row set derived from the detail View Object.
The presence of a View Link causes the detail View Object to be refreshed when
master View Object's current row designation changes. Whenever the master
row set iterator designates a new current row, the detail row set is
notified to refresh itself. The RowSetListener
objects
listening for the detail row set's events will receive the
rangeRefreshed()
event.
A View Link also affects initialization of the "foreign key" attribute of a detail row. When a new detail row is created its foreign key attribute is taken from the master row set iterator's current row.
A View Link can be defined in three different ways:
ViewObject
,
RowSet
,
RowSetIterator
,
RowSetListener
