Constructors

Constructor and Description
ProcessorCallbackI(ServiceFactoryI sf) Simplified constructor used to see if any usermode processor is active for either the current group or the current user.
ProcessorCallbackI(ServiceFactoryI sf, ResultHolder<omero.grid.ProcessorPrx> holder, omero.model.Job job) Primary constructor.

Method Summary

Modifier and Type	Method and Description
omero.grid.ProcessorPrx	activateAndWait(Ice.Current current) Generates a UUID-based Identity with the category of PROCESSORCALLBACK.value and then calls activateAndWait(Current, Ice.Identity).
omero.grid.ProcessorPrx	activateAndWait(Ice.Current current, Ice.Identity acceptId) Primary method which adds this instance to IceStorm, waits for a response from any active processor services, and finally unregister itself before returning the first processor instance which responded.
int	getResponses() Return the number of times this instance has been called in a thread safe manner.
void	isAccepted(boolean accepted, String sessionUuid, String procConn, Ice.Current __current) Deprecated.
void	isProxyAccepted(boolean accepted, String sessionUuid, omero.grid.ProcessorPrx procProxy, Ice.Current __current) Callback method called by the remote processor instance.
void	responseRunning(List<Long> jobIds, Ice.Current __current) Callback method which should not be called for this instance.

Constructor Detail

ProcessorCallbackI

public ProcessorCallbackI(ServiceFactoryI sf)

Simplified constructor used to see if any usermode processor is active for either the current group or the current user. Currently uses a hard-coded value of 5 seconds wait time. For more control, pass in a ResultHolder instance.

ProcessorCallbackI

public ProcessorCallbackI(ServiceFactoryI sf,
                          ResultHolder<omero.grid.ProcessorPrx> holder,
                          omero.model.Job job)

Primary constructor. Asks processors if they will accept the given job for the current user and the current group.

Parameters:

sf - Cannot be null.

holder - Cannot be null.

job - Can be null.

Method Detail

getResponses

public int getResponses()

Return the number of times this instance has been called in a thread safe manner.

Returns:

See above.

                                        throws omero.ServerError

Primary method which adds this instance to IceStorm, waits for a response from any active processor services, and finally unregister itself before returning the first processor instance which responded.

Parameters:

current -

acceptId -

Returns:

See above.

Throws:
