Method Details

supportsSsl

public boolean supportsSsl()

configure

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

finalize

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

close

public void close(io.netty.channel.Channel channel)

Description copied from interface: Channelizer

Called on Connection.closeAsync() to perform an Channelizer specific functions. Note that the Connection already calls Channel.close() so there is no need to call that method here. An implementation will typically use this method to send a Channelizer specific message to the server to notify of shutdown coming from the client side.

Specified by:

close in interface Channelizer

init

public void init(org.apache.tinkerpop.gremlin.driver.Connection connection)

Description copied from interface: Channelizer

Initializes the Channelizer. Called just after construction.

Specified by:

init in interface Channelizer

initChannel

protected void initChannel(io.netty.channel.socket.SocketChannel socketChannel)

Specified by:

initChannel in class io.netty.channel.ChannelInitializer<io.netty.channel.socket.SocketChannel>

connected

public void connected()

Description copied from interface: Channelizer

Called after the channel connects. The Channelizer may need to perform some functions, such as a handshake.

Specified by:

connected in interface Channelizer
