Interface EventListener

All Known Implementing Classes:

UPnP

public interface EventListener

Interface for receiving UPnP event notifications.

This interface defines the contract for objects that wish to receive event notifications from UPnP services. It provides a callback mechanism for handling incoming event messages containing state variable changes.

Key features:

• Event notification callback method
• Access to subscription UUID and sequence number
• Variable name and value information
• Real-time event handling capability

Implementations of this interface can register with UPnP control points to receive asynchronous notifications when subscribed services publish state variable changes, enabling responsive application behavior.

Method Summary
