All Implemented Interfaces:

PacketReceiver, AutoCloseable, org.jnetpcap.internal.PcapDispatcher, org.jnetpcap.PcapHandler, org.jnetpcap.PcapHandler.NativeCallback

public abstract class AbstractPacketReceiver
extends AbstractPcapDispatcher
implements PacketReceiver

AbstractPacketReceiver relies on preview features of the Java platform:

• AbstractPacketReceiver refers to one or more preview APIs: Arena, MemorySegment.

Programs can only use AbstractPacketReceiver when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
