public class SyncPacketCapture

extends PacketCapture

This class adds to PacketCapture the ability to explicitly terminate a capture session using close().

SyncPacketCapture utilizes libpcap's pcap_dispatch().

SyncPacketCapture inherits from the PacketCapture overriding its open(), capture() and close() methods in a way to keep synchronized the starting and the stopping phases of any capture() session . That allows close() method call to be performed any time from everywhere.
