cdac.medinfo.sdk.dcm30_04.services.scp.commons.SCPSession

Direct Known Subclasses:

TLSSCPSession

public class SCPSession
extends java.lang.Object

This class starts the SCP Session. SCPSession is responsible for accepting TCP connections from SCUs. It also maintains the Default capability of supported Presentation Contexts in the form of DefaultAssociation Before the SCPSession is started to listen for accepting connections, it is necessary to configure the SCPSession. This configuration involves adding the ProcessHandler,DefaultAssociation onto the SCPSession.

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 Session.

stopListening

public void stopListening()

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

getTimeOut

public int getTimeOut()

Returns setting for Socket read timeout of this session, 0 returns implies that the option is disabled (i.e., timeout of infinity).

Returns:

the setting for socket read timeout.

setTimeOut

public void setTimeOut(int itimeout)

sets Socket read timeout of this session, in milliseconds. With this option set to a non-zero timeout, a read() call on the InputStream associated with this Socket will block for only this amount of time.If the timeout expires, a session is closed,The timeout must be > 0. A timeout of zero is interpreted as an infinite timeout.

Parameters:

timeout - the specified timeout, in milliseconds.
