SCPController

public SCPController()
              throws java.io.IOException

Instantiates a new SCP controller.

Throws:

java.io.IOException - Signals that an I/O exception has occurred.

Method Detail

getDefaultAssociation

public DefaultAssociation getDefaultAssociation()

Gets the default association.

Returns:

DefaultAssociation - instance of default association

setDefaultAssociation

public void setDefaultAssociation(DefaultAssociation objDefaultAssociation)

Sets the default association.

Parameters:

objDefaultAssociation - instance of default association

getProcessHandler

public IProcessHandler getProcessHandler()

Gets the process handler.

Returns:

IProcessHandler - instance of process handler

setProcessHandler

public void setProcessHandler(IProcessHandler objIProcessHandler)

Sets process handler.

Parameters:

objIProcessHandler - instance of Process Handler.

accept

public void accept(java.net.SocketAddress objSocketAddress,
          int itimeout)
            throws java.io.IOException

Accepts the connection. For each connected client it creates a clientsession and perform call back to user process handler. If user sets the acceptance status as true for that client session only then it proceeds further else that request will be rejected and connection will be closed.

Parameters:

objSocketAddress - object of Socket Address.

Throws:

java.io.IOException - Signals that an I/O exception has occurred.

updateStatus

public void updateStatus(ClientSession objClientSession)

Update status of Client. This method removes the client from SCP when it goes down.

Specified by:

updateStatus in interface IClientStatusListener

Parameters:

objClientSession - object of client session.

noOfClientsConnected

public int noOfClientsConnected()

Retrieves number of clients currently connected to SCP.

Returns:

int - no. of Clients connected

isClientConnected

public boolean isClientConnected(java.net.InetSocketAddress objAddress)

Shows current status of client,whether it is active or not, for given Inet Socket Address

Parameters:

objAddress - InetSocketAddress of client

Returns:

boolean - shows status as true or false.

getClientsConnectionInfo

public ISingleCollection<java.net.InetSocketAddress> getClientsConnectionInfo()

Retrieves list of connection info for all currently active clients

Returns:

ISingleCollection - list of InetSocketAddress for all active clients

close

public void close()

Closes the SCP Controller.

stopListening

public void stopListening()

Stops listening on this SCPSession so that new client connection not accepted and continue to process already connected clients.
