com.hazelcast.nio.tcp.ProtocolEncoder

public class ProtocolEncoder
extends OutboundHandler<Void,ByteBuffer>

The ProtocolEncoder is responsible for writing the protocol and once the protocol has been written, the ProtocolEncoder is replaced by the appropriate handler. The ProtocolEncoder and the 'client' side of a member connection, will always write the cluster protocol immediately. The ProtocolEncoder on the 'server' side of the connection will wait till it has received the protocol and then will only send the protocol if the client side was a member.

Method Detail

handlerAdded

public void handlerAdded()

Description copied from class: ChannelHandler

Gets called when this ChannelHandler is added to the pipeline. This method should execute very quickly because it could be executed on an io thread. Will be called from a thread owning this handler.

Overrides:

handlerAdded in class ChannelHandler<OutboundHandler,Void,ByteBuffer>

onWrite

public HandlerStatus onWrite()

Description copied from class: OutboundHandler

A callback to indicate that this OutboundHandler should be processed. A OutboundHandler should be able to deal with a spurious wakeup. So it could be for example there is no frame for it to write to.

Specified by:

onWrite in class OutboundHandler<Void,ByteBuffer>

Returns:

HandlerStatus the status of the handler after processing the src.
