Description

Interface Summary

PacketCaptureCapable	This is the packet capture interface.
PacketDispatchCapable	An interface for classes capable of dispatching captured network packets.
PacketListener	Packet data listener.
RawPacketListener	Raw packet data listener.

Class Summary

CaptureStatistics	Packet capture statistics.
CaptureTest	Class to exercise PacketCapture.
PacketCapture	This class is the core of packet capture in jpcap.
PacketCaptureBase	This class contains base functionality shared by both the simulator and the actual packet capture system.
PacketDispatcher	This class encapsulates a mechanism for dispatching network data and packets to a listener who has subscribed to such events.
SyncPacketCapture	This class adds to PacketCapture the ability to explicitly terminate a capture session using close().

Exception Summary

CaptureConfigurationException	This exception occurs when the capture client tries to specify a capture device that does not exist or if the capture device specified is illegal.
CaptureDeviceInvalidException	This exception occurs when the capture client tries to specify a capture device that does not exist or if the capture device specified is illegal.
CaptureDeviceLookupException	This exception occurs when no capture devices are detected.
CaptureDeviceNotFoundException	This exception occurs when no capture devices are detected.
CaptureDeviceOpenException	This exception occurs when the capture device cannot be opened.
CaptureFileOpenException	This exception occurs when the savefile cannot be opened.
CapturePacketException	This exception occurs when an error occurs while capturing data.
InvalidFilterException	This exception occurs when an error occurs while capturing data.

Package net.sourceforge.jpcap.capture Description

Provides an interface for capturing packets and a layer of abstraction around libpcap, a portable native system library for capturing network packets.

PacketCapture is the core of the packet capture system provided by jpcap.

Applications wishing to capture network packets create an instance of PacketCapture and call its methods in order to open a network device, set packet filters and ultimately receive packet data from the network.

PacketCapture utilizes a publish/subscribe pattern to broadcast packets to all objects which have registered as listeners for events of interest. Applications capturing network data must implement PacketListener and register with an instance of the capture system in order to receive packets.
