Constructor and Description
PongResponse() Zero argument constructor used when unserializing an instance.
PongResponse(long pingStamp, Transport transport) Constructs a pong response which will use the supplied ping time to establish the end-to-end processing delay introduced by the server.

Method Summary

Modifier and Type	Method and Description
long	getPackStamp() Returns the time at which this packet was packed for delivery in the time frame of the server that sent the packet.
int	getProcessDelay() Returns the number of milliseconds that elapsed between the time that the ping which instigated this pong was read from the network and the time that this pong was written to the network.
Transport	getTransport() Returns the message transport parameters.
long	getUnpackStamp() Returns a timestamp that was obtained when this packet was decoded by the low-level networking code.

Constructor Detail

PongResponse

public PongResponse()

Zero argument constructor used when unserializing an instance.

PongResponse

public PongResponse(long pingStamp,
                    Transport transport)

Constructs a pong response which will use the supplied ping time to establish the end-to-end processing delay introduced by the server.

Method Detail

getPackStamp

public long getPackStamp()

Returns the time at which this packet was packed for delivery in the time frame of the server that sent the packet.

getProcessDelay

public int getProcessDelay()

Returns the number of milliseconds that elapsed between the time that the ping which instigated this pong was read from the network and the time that this pong was written to the network.

getUnpackStamp

public long getUnpackStamp()

Returns a timestamp that was obtained when this packet was decoded by the low-level networking code.

writeObject

public void writeObject(ObjectOutputStream out)
                 throws IOException

Writes our custom streamable fields.

Throws:

IOException

readObject

public void readObject(ObjectInputStream in)
                throws IOException,
                       ClassNotFoundException

Reads our custom streamable fields.

Throws:

IOException

ClassNotFoundException

setTransport

public void setTransport(Transport transport)

Description copied from class: Message

Sets the message transport parameters. For messages received over the network, these describe the mode of transport over which the message was received. When sending messages, they act as a hint as to the type of transport desired. Calling this method may have no effect, depending on whether non-default modes of transport are supported for this message type.

Overrides:

setTransport in class Message

getTransport

public Transport getTransport()

Description copied from class: Message

Returns the message transport parameters.

Overrides:

getTransport in class Message

toString

public String toString()

Overrides:

toString in class DownstreamMessage
