Interface ILcdKML22ResourceListener

public interface ILcdKML22ResourceListener

A resource listener is notified of changes to a resource. This interface is typically used in KML to signal when the loading of a resource asynchronously has finished, or when an existent resource has been updated.

This interface features two mutual exclusive methods:

• resourceAvailable -> When the change to the resource was a success
• resourceNotAvailable -> When the change to the resource was unsuccessful

The reason these methods are mutual exclusive is because when a notifier sends an event, it will send either a resourceAvailable event or a resourceNotAvailable event, for each individual asynchronous retrieve or update.
