Method Detail

messageReceived

public void messageReceived(org.jboss.netty.channel.ChannelHandlerContext ctx,
                   org.jboss.netty.channel.MessageEvent e)
                     throws java.lang.Exception

Overrides:

messageReceived in class org.jboss.netty.channel.SimpleChannelUpstreamHandler

Throws:

java.lang.Exception

createHostPort

protected HostPort createHostPort(org.jboss.netty.channel.ChannelHandlerContext ctx)

Creates the host port.

Parameters:

ctx - the ctx

Returns:

the host port

channelConnected

public void channelConnected(org.jboss.netty.channel.ChannelHandlerContext ctx,
                    org.jboss.netty.channel.ChannelStateEvent e)
                      throws java.lang.Exception

Invoked when a Channel is open, bound to a local address, and connected to a remote address.
Be aware that this event is fired from within the Boss-Thread so you should not execute any heavy operation in there as it will block the dispatching to other workers!

Overrides:

channelConnected in class org.jboss.netty.channel.SimpleChannelUpstreamHandler

Parameters:

ctx - the ctx

e - the e

Throws:

java.lang.Exception - the exception

channelDisconnected

public void channelDisconnected(org.jboss.netty.channel.ChannelHandlerContext ctx,
                       org.jboss.netty.channel.ChannelStateEvent e)
                         throws java.lang.Exception

Invoked when a Channel was disconnected from its remote peer.

Overrides:

channelDisconnected in class org.jboss.netty.channel.SimpleChannelUpstreamHandler

Parameters:

ctx - the ctx

e - the e

Throws:

java.lang.Exception - the exception

getConnectedHostPorts

public java.util.Set<HostPort> getConnectedHostPorts()

Gets the connected host ports.

Returns:

the connected host ports

isConnected

public boolean isConnected(HostPort hostPort)

Checks if is connected.

Parameters:

hostPort - the host port

Returns:

true, if is connected

broadcastMessage

public void broadcastMessage(java.lang.String message)
