Method Detail

getEventLoopGroup

public NioEventLoopGroup getEventLoopGroup()

initEventLoopGroup

protected NioEventLoopGroup initEventLoopGroup(HazelcastClientInstanceImpl client)

getActiveConnections

public Collection<ClientConnection> getActiveConnections()

Specified by:

getActiveConnections in interface ClientConnectionManager

isAlive

public boolean isAlive()

Description copied from interface: ClientConnectionManager

Check if client connection manager is alive. ClientConnectionManager is not alive only when client is closing.

Specified by:

isAlive in interface ClientConnectionManager

Returns:

true if alive, false otherwise.

start

public void start(ClientContext clientContext)

startEventLoopGroup

protected void startEventLoopGroup()

shutdown

public void shutdown()

getPrincipal

public ClientPrincipal getPrincipal()

Specified by:

getPrincipal in interface ClientConnectionManager

stopEventLoopGroup

protected void stopEventLoopGroup()

getActiveConnection

public Connection getActiveConnection(Address target)

Specified by:

getActiveConnection in interface ClientConnectionManager

Parameters:

target - to be connected

Returns:

connection if available, null otherwise

getOrConnect

public Connection getOrConnect(Address address)
                        throws IOException

Specified by:

getOrConnect in interface ClientConnectionManager

Parameters:

address - to be connected

Returns:

associated connection if available, creates new connection otherwise

Throws:

IOException - if connection is not established

getOrTriggerConnect

public Connection getOrTriggerConnect(Address target,
                                      boolean acquiresResources)
                               throws IOException

Specified by:

getOrTriggerConnect in interface ClientConnectionManager

Parameters:

target - to be connected

Returns:

associated connection if available, returns null and triggers new connection creation otherwise

Throws:

IOException - if connection is not able to triggered

getOwnerConnectionAddress

public Address getOwnerConnectionAddress()

Specified by:

getOwnerConnectionAddress in interface ClientConnectionManager

getOwnerConnection

public ClientConnection getOwnerConnection()

Specified by:

getOwnerConnection in interface ClientConnectionManager

Parameters:

connectionListener - the ConnectionListener to add.

addConnectionHeartbeatListener

public void addConnectionHeartbeatListener(ConnectionHeartbeatListener connectionHeartbeatListener)

Specified by:

addConnectionHeartbeatListener in interface ClientConnectionManager

heartbeatResumed

public void heartbeatResumed(Connection connection)
