public class ConversionEvent

extends BaseEvent

This class is the event that is generated when a bean property is being set AND the value is being automatically converted.

The getOldValue and getNewValue methods in BaseEvent class are different for this event and are described here:

getOldValue - Returns the value of the parameter that is being converted BEFORE it is converted. This value will remain the same for the pre, post and failed conversion events.

getNewValue - Returns the value of the parameter that is being converted AFTER it is converted. For pre-conversion events this will be equal to the value of getOldValue because the conversion has not yet taken place. For post-conversion events, this will have the value of the parameter AFTER it has been converted. For failed-conversion events, this will be equal to the value of getOldValue because the conversion failed before completing.

It is also important to remember that if a conversion fails, only the pre-conversion and failed-conversion events will occur. If the conversion succeeded, then only the pre-conversion and post-conversion events will occur.
