Method Details

receive

public void receive(Message.Mutable message,
 Promise<Void> promise)

Description copied from class: AbstractClientSession

Receives a message (from the server) and process it.

Processing the message involves calling the receive extensions and the channel listeners.

Overrides:

receive in class AbstractClientSession

Parameters:

message - the message received.

promise - the promise notified of the receive processing

newChannel

protected AbstractClientSession.AbstractSessionChannel newChannel(ChannelId channelId)

Specified by:

newChannel in class AbstractClientSession

newChannelId

protected ChannelId newChannelId(String channelId)

Specified by:

newChannelId in class AbstractClientSession

sendBatch

protected void sendBatch()

Specified by:

sendBatch in class AbstractClientSession

getServerSession

public ServerSession getServerSession()

Specified by:

getServerSession in interface LocalSession

Returns:

the associated ServerSession

handshake

public void handshake(Map<String,Object> template,
 ClientSession.MessageListener callback)

Description copied from interface: ClientSession

Initiates the bayeux protocol handshake with the server(s).

The handshake initiated by this method is asynchronous and does not wait for the handshake response.

Specified by:

handshake in interface ClientSession

Parameters:

template - additional fields to add to the handshake message.

callback - the message listener to notify of the handshake result

disconnect

public void disconnect(ClientSession.MessageListener callback)

Description copied from interface: ClientSession

Disconnects this session, ending the link between the client and the server peers.

Specified by:

disconnect in interface ClientSession

Parameters:

callback - the message listener to notify of the disconnect result

getId

public String getId()

Description copied from interface: Session

The clientId of the session.

This would more correctly be called a "sessionId", but for backwards compatibility with the Bayeux protocol, it is a field called "clientId" that identifies a session.

Specified by:

getId in interface Session

Returns:

the id of this session

isConnected

public boolean isConnected()

Description copied from interface: Session

A connected session is a session where the link between the client and the server has been established.

Specified by:

isConnected in interface Session

Returns:

whether the session is connected

See Also:

• Session.disconnect()

isHandshook

public boolean isHandshook()

Description copied from interface: Session

A handshook session is a session where the handshake has successfully completed

Specified by:

isHandshook in interface Session

Returns:

whether the session is handshook

toString

public String toString()

Overrides:

toString in class Object

send

protected void send(Message.Mutable message)

Specified by:

send in class AbstractClientSession

send

protected void send(ServerSessionImpl session,
 ServerMessage.Mutable message)

Enqueues or sends a message to the server.

This method will either enqueue the message, if this session is batching, or perform the send immediately.

Parameters:

session - The ServerSession to send as. This normally the current server session, but during handshake it is a proposed server session.

message - The message to send.

newMessage

protected ServerMessage.Mutable newMessage()

Overrides:

newMessage in class AbstractClientSession
