Class MMNotificationClient

java.lang.Object

org.jitsi.impl.neomedia.jmfext.media.protocol.wasapi.MMNotificationClient

public class MMNotificationClient
extends Object

Implements the Java counterpart of an IMMNotificationClient instance statically allocated by the native counterpart of WASAPI and automatically registered with all IMMDeviceEnumerator instances. Invocations of methods on the IMMNotificationClient instance by Windows Audio Session API (WASAPI) are forwarded by WASAPI to the respective static methods of the MMNotificationClient class.
