Class HandlerState

java.lang.Object

biz.onixs.eurex.eti.handler.core.HandlerState

public class HandlerState
extends Object

A state of the Handler, reported to HandlerStateListener on every transition.

The handler moves between these states only along the following edges:

 NOT_INITED    -> DISCONNECTED
 DISCONNECTED  -> NOT_INITED | CONNECTING
 CONNECTING    -> CONNECTED  | DISCONNECTED
 CONNECTED     -> DISCONNECTING | DISCONNECTED
 DISCONNECTING -> DISCONNECTED
 

DISCONNECTING is published whenever an established session is being torn down - after a disconnect(), and equally after a connection loss, whether or not a graceful logout was possible. The CONNECTED to DISCONNECTED edge exists for completeness and is not taken when a live session ends; a connect attempt that never established one settles from CONNECTING instead.

Instances are singletons and may be compared with ==.
