Method Detail

init

protected void init()
             throws Exception

Initialize the polling system, will be called at construction time.

Specified by:

init in class AbstractPollingIoConnector<AprSession,Long>

Throws:

Exception - any exception thrown by the underlying system calls

destroy

protected void destroy()
                throws Exception

Destroy the polling system, will be called when this IoConnector implementation will be disposed.

Specified by:

destroy in class AbstractPollingIoConnector<AprSession,Long>

Throws:

Exception - any exception thrown by the underlying systems calls

allHandles

protected Iterator<Long> allHandles()

Iterator for all the client sockets polled for connection.

Specified by:

allHandles in class AbstractPollingIoConnector<AprSession,Long>

Returns:

the list of client sockets currently polled for connection

connect

protected boolean connect(Long handle,
                          SocketAddress remoteAddress)
                   throws Exception

Connect a newly created client socket handle to a remote SocketAddress. This operation is non-blocking, so at end of the call the socket can be still in connection process.

Specified by:

connect in class AbstractPollingIoConnector<AprSession,Long>

Parameters:

handle - the client socket handle

remoteAddress - the remote address where to connect

Returns:

true if a connection was established, false if this client socket is in non-blocking mode and the connection operation is in progress

Throws:

Exception

connectionRequest

protected AbstractPollingIoConnector.ConnectionRequest connectionRequest(Long handle)

get the AbstractPollingIoConnector.ConnectionRequest for a given client socket handle

Specified by:

connectionRequest in class AbstractPollingIoConnector<AprSession,Long>

Parameters:

handle - the socket client handle

Returns:

the connection request if the socket is connecting otherwise null

close

protected void close(Long handle)
              throws Exception

Close a client socket.

Specified by:

close in class AbstractPollingIoConnector<AprSession,Long>

Parameters:

handle - the client socket

Throws:

Exception - any exception thrown by the underlying systems calls

finishConnect

protected boolean finishConnect(Long handle)
                         throws Exception

Finish the connection process of a client socket after it was marked as ready to process by the AbstractPollingIoConnector.select(int) call. The socket will be connected or reported as connection failed.

Specified by:

finishConnect in class AbstractPollingIoConnector<AprSession,Long>

Parameters:

handle - the client socket handle to finsh to connect

Returns:

true if the socket is connected

Throws:

Exception - any exception thrown by the underlying systems calls

newHandle

protected Long newHandle(SocketAddress localAddress)
                  throws Exception

Create a new client socket handle from a local SocketAddress

Specified by:

Parameters:

localAddress - the socket address for binding the new client socket

Returns:

a new client socket handle

Throws:

Exception - any exception thrown by the underlying systems calls
