Class RowMessageBoundValue

  +--oracle.cabo.ui.data.bind.RowMessageBoundValue

All Implemented Interfaces:

BoundValue

public class RowMessageBoundValue

extends java.lang.Object

implements BoundValue

The RowMessageBoundValue class greatly simplifies the process of adding inline messages to a table.

Each row of a table already has a "current DataObject". Now, for each row of the table that needs an inline message, add to the "current DataObject" one more Object at a fixed key. RowMessageBoundValue will let you use that Object as the "real" key for inline messaging.

In practice, this class can be used for more than tables; it can be used in any cases where the message key used for a node should be computed indirectly.
