com.fr.third.jgroups.demos.QuoteClient

所有已实现的接口:

MembershipListener, java.awt.event.ActionListener, java.awt.event.WindowListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible

public class QuoteClient
extends java.awt.Frame
implements java.awt.event.WindowListener, java.awt.event.ActionListener, MembershipListener

Used in conjunction with QuoteServer: a client is member of a group of quote servers which replicate stock quotes among themselves. The client broadcasts its request (set, get quotes) and (in the case of get waits for the first reply received (usually the one from the quote server closest to it). The client can get and set quotes as long as a minimum of 1 server (in the group) is running.

setQuote

public void setQuote(java.lang.String stock_name,
            java.lang.Float value)

printAllStocks

public void printAllStocks()

viewAccepted

public void viewAccepted(View new_view)

从接口复制的说明: MembershipListener

Called when a change in membership has occurred. No long running actions, sending of messages or anything that could block should be done in this callback. If some long running action needs to be performed, it should be done in a separate thread.

Note that on reception of the first view (a new member just joined), the channel will not yet be in the connected state. This only happens when Channel.connect(String) returns.

指定者:

viewAccepted 在接口中 MembershipListener

suspect

public void suspect(Address suspected_mbr)

从接口复制的说明: MembershipListener

Called whenever a member is suspected of having crashed, but has not yet been excluded.

指定者:

suspect 在接口中 MembershipListener

block

public void block()

从接口复制的说明: MembershipListener

Called (usually by the FLUSH protocol), as an indication that the member should stop sending messages. Any messages sent after returning from this callback might get blocked by the FLUSH protocol. When the FLUSH protocol is done, and messages can be sent again, the FLUSH protocol will simply unblock all pending messages. If a callback for unblocking is desired, implement MembershipListener.unblock(). Note that block() is the equivalent of reception of a BlockEvent in the pull mode.

指定者:

block 在接口中 MembershipListener

unblock

public void unblock()

从接口复制的说明: MembershipListener

Called after the FLUSH protocol has unblocked previously blocked senders, and messages can be sent again. This callback only needs to be implemented if we require a notification of that.

Note that during new view installation we provide guarantee that unblock invocation strictly follows view installation at some node A belonging to that view . However, some other message M may squeeze in between view and unblock callbacks.

For more details see https://jira.jboss.org/jira/browse/JGRP-986

指定者:

unblock 在接口中 MembershipListener

main

public static void main(java.lang.String[] args)
