Constructor Detail

TextDecoder

public TextDecoder(TcpIpConnection connection,
                   TextEncoder encoder,
                   com.hazelcast.internal.nio.ascii.TextProtocolFilter textProtocolFilter,
                   TextParsers textParsers,
                   boolean rootDecoder)

Method Detail

sendResponse

public void sendResponse(TextCommand command)

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<InboundHandler,ByteBuffer,Void>

onRead

public HandlerStatus onRead()
                     throws Exception

Description copied from class: InboundHandler

A callback to indicate that data is available in the src to be processed. InboundHandlers should be able to deal with spurious onReads (so a read even though there is nothing to be processed).

Specified by:

onRead in class InboundHandler<ByteBuffer,Void>

Returns:

HandlerStatus the status of the handler after processing the src.

Throws:

Exception - if something fails while reading data from the src or processing the data (e.g. when a Packet fails to get processed). When an exception is thrown, the ChannelErrorHandler is called.

publishRequest

public void publishRequest(TextCommand command)

getEncoder

public TextEncoder getEncoder()

closeConnection

public void closeConnection()
