Class ClientReadHandler

java.lang.Object

com.hazelcast.nio.tcp.ClientReadHandler

All Implemented Interfaces:

ClientMessageReadHandler.MessageHandler, ReadHandler

public class ClientReadHandler
extends Object
implements ReadHandler, ClientMessageReadHandler.MessageHandler

A ReadHandler for the new-client. It passes the ByteBuffer to the ClientMessageReadHandler. For each constructed ClientMessage, the handleMessage(ClientMessage) is called; which passes the message to the IOService.handleClientMessage(ClientMessage, Connection). Probably the design can be simplified if the IOService would expose a method getMessageHandler; so we don't need to let the ClientReadHandler act like the MessageHandler, but directly send to the right data-structure.

Constructor Detail

ClientReadHandler

public ClientReadHandler(SwCounter messageCounter,
                         Connection connection,
                         IOService ioService)

Throws:

IOException

Method Detail

onRead

public void onRead(ByteBuffer src)
            throws Exception

Description copied from interface: ReadHandler

A callback to indicate that data is available in the ByteBuffer to be processed.

Specified by:

onRead in interface ReadHandler

Parameters:

src - the ByteBuffer containing the data to read. The ByteBuffer is already in reading mode and when completed, should not be converted to write-mode using clear/compact. That is a task of the SocketReader.

Throws:

Exception - if something fails while reading data from the ByteBuffer or processing the data (e.g. when a Packet fails to get processed). When an exception is thrown, the TcpIpConnection is closed. There is no point continuing with a potentially corrupted stream.

handleMessage

public void handleMessage(ClientMessage message)

Description copied from interface: ClientMessageReadHandler.MessageHandler

Received message to be processed

Specified by:

handleMessage in interface ClientMessageReadHandler.MessageHandler

Parameters:

message - the ClientMessage
