Method Summary

Modifier and Type	Method and Description
void	configure(io.netty.channel.ChannelPipeline pipeline) This method is called from within AbstractChannelizer.initChannel(SocketChannel) just after the SSL handler is put in the pipeline.
Object	createIdleDetectionMessage() Create a message to send to seemingly dead clients to see if they respond back.
void	finalize(io.netty.channel.ChannelPipeline pipeline) This method is called after the pipeline is completely configured.
UnifiedHandler	getUnifiedHandler()
void	init(ServerGremlinExecutor serverGremlinExecutor) This method is called just after the Channelizer is initialized.
boolean	supportsIdleMonitor() Determines if the channelizer supports a method for keeping the connection alive and auto-closing zombie channels.

Method Detail

init

public void init(ServerGremlinExecutor serverGremlinExecutor)

Description copied from interface: Channelizer

This method is called just after the Channelizer is initialized.

Specified by:

init in interface Channelizer

Overrides:

init in class AbstractChannelizer

configure

public void configure(io.netty.channel.ChannelPipeline pipeline)

Description copied from class: AbstractChannelizer

This method is called from within AbstractChannelizer.initChannel(SocketChannel) just after the SSL handler is put in the pipeline. Modify the pipeline as needed here.

Specified by:

configure in class AbstractChannelizer

finalize

public void finalize(io.netty.channel.ChannelPipeline pipeline)

Description copied from class: AbstractChannelizer

This method is called after the pipeline is completely configured. It can be overridden to make any final changes to the pipeline before it goes into use.

Overrides:

finalize in class AbstractChannelizer

getUnifiedHandler

public UnifiedHandler getUnifiedHandler()

supportsIdleMonitor

public boolean supportsIdleMonitor()

Description copied from interface: Channelizer

Determines if the channelizer supports a method for keeping the connection alive and auto-closing zombie channels.

createIdleDetectionMessage

public Object createIdleDetectionMessage()

Description copied from interface: Channelizer

Create a message to send to seemingly dead clients to see if they respond back. The message sent will be dependent on the implementation. For example, a websocket implementation would create a "ping" message. This method will only be used if Channelizer.supportsIdleMonitor() is true.
