com.marketfactory.messaging.HeartbeatMessage

All Implemented Interfaces:

IMessage, java.io.Serializable, java.lang.Comparable<HeartbeatMessage>

public final class HeartbeatMessage
extends java.lang.Object
implements IMessage, java.lang.Comparable<HeartbeatMessage>, java.io.Serializable

A streaming heartbeat message which contians a mask of currently active feeds. This message is sent at a regular interval, not upon heartbeat requests. We implemented this for some clients which requested high-frequency heartbeats (e.g. every 10ms).
