Method Detail

isEnabled

public static boolean isEnabled(XMPPIOService service)

Method returns true if XMPPIOService has enabled SM.

Parameters:

service -

getId

public String getId()

Description copied from interface: XMPPIOProcessor

Returns identifier of processor

Specified by:

getId in interface XMPPIOProcessor

setConnectionManager

public void setConnectionManager(ConnectionManager connectionManager)

Description copied from interface: XMPPIOProcessor

Sets connection manager instance for which this XMPPIOProcessor is used

Specified by:

setConnectionManager in interface XMPPIOProcessor

supStreamFeatures

public tigase.xml.Element[] supStreamFeatures(XMPPIOService service)

Description copied from interface: XMPPIOProcessor

Returns array of features added by this processor

Specified by:

supStreamFeatures in interface XMPPIOProcessor

processIncoming

public boolean processIncoming(XMPPIOService service,
                      Packet packet)

Description copied from interface: XMPPIOProcessor

Process packets read from socket as they are sent to SessionManager.

Specified by:

processIncoming in interface XMPPIOProcessor

Returns:

true if packet should not be forwarded

processOutgoing

public boolean processOutgoing(XMPPIOService service,
                      Packet packet)

Description copied from interface: XMPPIOProcessor

Process outgoing packets as they are added to XMPPIOService outgoing packets queue.

Specified by:

processOutgoing in interface XMPPIOProcessor

Returns:

true if packet should be removed

packetsSent

public void packetsSent(XMPPIOService service)
                 throws IOException

Description copied from interface: XMPPIOProcessor

Method is called when all waiting data was written to socket.

Specified by:

packetsSent in interface XMPPIOProcessor

Throws:

IOException

shouldRequestAck

protected boolean shouldRequestAck(XMPPIOService service,
                       StreamManagementIOProcessor.OutQueue outQueue)

Override this method to define a custom behaviour for request ack. The default implementation will request an ack if there are more than ack_request_count packets waiting, so you probably want to OR your behaviour with this.

processCommand

public void processCommand(XMPPIOService service,
                  Packet pc)

Description copied from interface: XMPPIOProcessor

Process command execution which may be sent from other component and should be processed by processor

Specified by:

processCommand in interface XMPPIOProcessor

serviceStopped

public boolean serviceStopped(XMPPIOService service,
                     boolean streamClosed)

Description copied from interface: XMPPIOProcessor

Method called when XMPPIOService is closed.

Specified by:

serviceStopped in interface XMPPIOProcessor

Returns:

true if connecton manager should not be notified about stopping of this service

setProperties

public void setProperties(Map<String,Object> props)

Description copied from interface: XMPPIOProcessor

Method used for setting properties

Specified by:

setProperties in interface XMPPIOProcessor

newCounter

protected StreamManagementIOProcessor.Counter newCounter()

newOutQueue

protected StreamManagementIOProcessor.OutQueue newOutQueue()
