Method Summary

Modifier and Type	Method and Description
Object	doWork(org.hibernate.Session session, ServiceFactory sf) Loads reps EventLog instances and returns them.
protected Pixels	getPixels(Long id, ServiceFactory sf)
void	handleEventLog(EventLog eventLog, org.hibernate.Session session, ServiceFactory sf) Handles only single elements from the PersistentEventLogLoader in order to keep transactions short and safe.
boolean	process(Long id, ServiceFactory sf, org.hibernate.Session s) Here we assume that our log loader will only return us the proper types, since we are using the specific type defined in this package.
void	setRepetitions(int reps) Spring injector.
void	setSqlAction(SqlAction sql) Since these instances are used repeatedly, we need to check for already set SqlAction

loader

protected final PixelsService pixelsService

reps

protected int reps

Constructor Detail

PixelDataHandler

public PixelDataHandler(EventLogLoader ll,
                        PixelsService pixelsService)

Method Detail

setRepetitions

public void setRepetitions(int reps)

Spring injector. Sets the number of indexing runs will be made if there is a substantial backlog.

setSqlAction

public void setSqlAction(SqlAction sql)

Since these instances are used repeatedly, we need to check for already set SqlAction

Overrides:

setSqlAction in class Executor.SimpleWork

doWork

@Transactional(readOnly=false)
public Object doWork(org.hibernate.Session session,
                                                    ServiceFactory sf)

Loads reps EventLog instances and returns them. This is the first phase used by the PixelDataThread. A later phase will invoke handleEventLog(EventLog, Session, ServiceFactory) with the returned instance.

Parameters:

session - non null.

sf - non null.

Returns:

Any results which will be used by non-wrapped code.

handleEventLog

public void handleEventLog(EventLog eventLog,
                           org.hibernate.Session session,
                           ServiceFactory sf)

Handles only single elements from the PersistentEventLogLoader in order to keep transactions short and safe.

process

public boolean process(Long id,
                       ServiceFactory sf,
                       org.hibernate.Session s)

Here we assume that our log loader will only return us the proper types, since we are using the specific type defined in this package.

Parameters:

id -

sf -

s -

Returns:

See above.

getPixels

protected Pixels getPixels(Long id,
                           ServiceFactory sf)
