Method Detail

doInit

protected void doInit()
               throws org.apache.axis2.AxisFault

Description copied from class: AbstractTransportListenerEx

Initialize the transport. This method will be called after the initialization work in AbstractTransportListener and before the first endpoint is created, i.e. before the first call to AbstractTransportListenerEx.createEndpoint().

Specified by:

doInit in class AbstractTransportListenerEx<T extends AbstractPollTableEntry>

Throws:

org.apache.axis2.AxisFault

destroy

public void destroy()

Specified by:

destroy in interface org.apache.axis2.transport.TransportListener

Overrides:

destroy in class AbstractTransportListener

startEndpoint

protected void startEndpoint(T endpoint)
                      throws org.apache.axis2.AxisFault

Specified by:

startEndpoint in class AbstractTransportListenerEx<T extends AbstractPollTableEntry>

Throws:

org.apache.axis2.AxisFault

stopEndpoint

protected void stopEndpoint(T endpoint)

Specified by:

stopEndpoint in class AbstractTransportListenerEx<T extends AbstractPollTableEntry>

poll

protected abstract void poll(T entry)

onPollCompletion

protected void onPollCompletion(T entry)

processFailure

protected void processFailure(String msg,
                  Exception e,
                  T entry)

method to log a failure to the log file and to update the last poll status and time

Parameters:

msg - text for the log message

e - optional exception encountered or null

entry - the PollTableEntry

pause

public void pause()
           throws org.apache.axis2.AxisFault

Pause the listener - Stop accepting/processing new messages, but continues processing existing messages until they complete. This helps bring an instance into a maintenence mode

Overrides:

pause in class AbstractTransportListener

Throws:

org.apache.axis2.AxisFault - on error

resume

public void resume()
            throws org.apache.axis2.AxisFault

Resume the lister - Brings the lister into active mode back from a paused state

Overrides:

resume in class AbstractTransportListener

Throws:

org.apache.axis2.AxisFault - on error

maintenenceShutdown

public void maintenenceShutdown(long millis)
                         throws org.apache.axis2.AxisFault

Stop processing new messages, and wait the specified maximum time for in-flight requests to complete before a controlled shutdown for maintenence

Overrides:

maintenenceShutdown in class AbstractTransportListener

Parameters:

millis - a number of milliseconds to wait until pending requests are allowed to complete

Throws:

org.apache.axis2.AxisFault - on error
