Class ValidationEvent

java.lang.Object
  java.util.EventObject
      oracle.dacf.dataset.ValidationEvent

All Implemented Interfaces:

java.io.Serializable

public class ValidationEvent

extends java.util.EventObject

ValidationEvents are fired by an InfoObject in order to:

• Validate a DataItem bound to a Control.
• Approve a navigation from one DataItem to another.

A ValidationEvent describes:

• the level of validation to be performed. Validation levels range from InfoObject.LEVEL_COLUMN to InfoObject.LEVEL_APPLICATION.
• name of the DataItem to be validated.

ValidationEvents are veteoable and are fired before the navigation events. A listener (which implements the ValidationListener interface) can veto the ValidationEvent by throwing a ValidationException. Vetoing the event disapproves the navigation change.
