org.opennms.netmgt.icmp.jna.JnaPingReply

All Implemented Interfaces:

Response, ResponseWithId<JnaPingRequestId>, EchoPacket

public final class JnaPingReply
extends Object
implements ResponseWithId<JnaPingRequestId>, EchoPacket

This class is use to encapsulate an ICMP reply that conforms to the packetclass. The reply must be of type ICMP Echo Reply and be the correct length.

When constructed by the create method the returned reply encapsulates the sender's address and the received packet as final, non-mutable values for the instance.
