PersistentEventLogLoader (omero-server 5.5.3 API)

java.lang.Object
- ome.services.eventlogs.EventLogLoader
- - ome.services.eventlogs.PersistentEventLogLoader
  - - ome.services.pixeldata.PersistentEventLogLoader

All Implemented Interfaces:

java.lang.Iterable<ome.model.meta.EventLog>, java.util.EventListener, java.util.Iterator<ome.model.meta.EventLog>, org.springframework.context.ApplicationListener
```
public class PersistentEventLogLoader
extends PersistentEventLogLoader
```
EventLogLoader implementation which keeps tracks of the last EventLog instance, and always provides the next unindexed instance. Resetting that saved value would restart indexing.

Since:

Beta4.3

public void initialize()

    Description copied from class: PersistentEventLogLoader
    
    Called when the configuration database does not contain a valid current_id.
    
    Specified by:
    
    initialize in class PersistentEventLogLoader
  - query
```
protected ome.model.meta.EventLog query()
```
    Uses data from the dataPerUser "queue" to allow new requests to be processed even if one user adds a large number of PIXELDATA events. Only the lowest event log id will be saved as the PersistentEventLogLoader.getCurrentId() meaning that some event logs will be processed multiple times. The call to create the pyramid must properly ignore existing pyramids.
    
    Overrides:
    
    query in class PersistentEventLogLoader
  - available
```
protected boolean available()
```
  - pop
```
protected ome.model.meta.EventLog pop()
