Class Destination<T>

java.lang.Object

org.thales.punch.libraries.netty.groups.Destination<T>

Type Parameters:

T - the type of data read by the client. Plain TCP use String, Lumberjack use Map<String,String>.

All Implemented Interfaces:

Comparable<Destination<T>>, INettyConnectionCallback

public class Destination<T>
extends Object
implements INettyConnectionCallback, Comparable<Destination<T>>

A destination encapsulate a Netty TCP client. Either a plain one or a Lumberjack one. It has an associated weight and belongs to a group.

Besides, it registers a connection callback to be told upon connection/disconnection of the underlying client. That is used to update the status (i.e. total weight) of the group.
