Member Function Documentation

void com.pcbsys.nirvana.client.p2p.nOutOfBandService.close (  ) 

Closes the OOB session with the remote P2P service.

It does NOT close the main p2p service

Reimplemented from com.pcbsys.nirvana.client.p2p.nService.

void com.pcbsys.nirvana.client.p2p.nOutOfBandService.deregisterListener ( final nEventServiceListener  listener  )  throws IOException

Removes the registered nEventServiceListener from this service.

When all listeners are removed then the read() method can then be called

Parameters:
listener an nEventServiceListener to stop getting the callbacks
Exceptions:
IOException if Service is closed or listener is null

nConsumeEvent com.pcbsys.nirvana.client.p2p.nOutOfBandService.read ( final long  timeout  )  throws IOException

Waits for a new nConsumeEvent to be received from the remote service or the timeout to be reached.

Parameters:
timeout Time in milliseconds to wait for the event to be received
Returns:
nConsumeEvent received from the remote service
Exceptions:
IOException if the lower streams have an error, See the message or more information

nConsumeEvent com.pcbsys.nirvana.client.p2p.nOutOfBandService.read (  )  throws IOException

Waits for a new nConsumeEvent to be received from the remote service.

Returns:
nConsumeEvent received from the remote service
Exceptions:
IOException if the lower streams have an error, See the message or more information

void com.pcbsys.nirvana.client.p2p.nOutOfBandService.registerListener ( final nEventServiceListener  listener  )  throws IOException

Registers an nEventServiceListener with this class.

This nEventServiceListener will be called whenever there is a new event received

Once this is called then this will preclude the use of the read() method

Parameters:
listener an nEventServiceListener to receive the callbacks
Exceptions:
IOException if Service is closed or listener is null

void com.pcbsys.nirvana.client.p2p.nOutOfBandService.write ( final nConsumeEvent  evt  )  throws IOException

Writes an nConsumeEvent to the remote P2P service.

Parameters:
evt An nConsumeEvent to send to the remote service
Exceptions:
IOException if the lower streams have an error, See the message or more information
