Method Detail

getRoundtrips

public int getRoundtrips()

Description copied from interface: TransportProviderI

Returns the current number of client-server roundtrips.

Specified by:

getRoundtrips in interface TransportProviderI

getSessionId

public java.lang.Long getSessionId(boolean blockUntilAvailable)

Description copied from interface: TransportProviderI

Returns the Id of the current server-connection. If blockUntilAvailable is true, will wait until our connection is authenticated at the server.

Specified by:

getSessionId in interface TransportProviderI

getTransport

public TransportI getTransport(java.lang.String reason,
                               boolean needAuth)
                        throws ServerConnectionException

Description copied from interface: TransportProviderI

Returns a usable TransportI for client-server communication. If blockUntilAvailable is true, will wait until our connection is authenticated at the server.

Specified by:

getTransport in interface TransportProviderI

Throws:

ServerConnectionException

releaseTransport

public void releaseTransport(TransportI t,
                             java.lang.Exception e)
                      throws ServerConnectionException,
                             java.lang.IllegalStateException

Description copied from interface: TransportProviderI

Releases the passed TransportI again. The passed Exception is the reason for the release and may be null.

Specified by:

releaseTransport in interface TransportProviderI

Throws:

ServerConnectionException

java.lang.IllegalStateException

startWorker

public void startWorker()

Description copied from interface: TransportProviderI

Starts the worker thread of this TransportProviderI, which performs maintenance on the managed TransportI-s.

Specified by:

startWorker in interface TransportProviderI
