net.sourceforge.jpcap.capture.PacketCapture

This class is the core of packet capture in jpcap. It provides a high-level interface for capturing network packets by encapsulating libpcap.

If you want to capture network packets, implement PacketListener and register with an instance of this class. When packets arrive, the object will call you back via packetArrived().

Examples can be found in net.sourceforge.jpcap.tutorial.

For more documentation on this class's methods, see PacketCaptureCapable; Javadoc is 'inherited' from this interface.

PacketCapture utilizes libpcap's pcap_loop(). See SyncPacketCapture for pcap_dispatch()-type behavior. @author Patrick Charles and Jonas Lehmann @version $Revision: 1.16 $ @lastModifiedBy $Author: pcharles $ @lastModifiedAt $Date: 2004/09/28 17:27:11 $

                // Step 2:  Check for devices
                System.out.println("Capturing on "+m_device);


                // Step 3:  Open Device for Capturing (requires root)
