java.lang.Objectome.services.fulltext.EventLogLoader
public abstract class EventLogLoader
Data access object for the FullTextIndexer
which provides an
Iterator
interface for EventLog
instances to be properly
indexed. Also supports the concept of batches. After batchSize
queries,

public void setBatchSize(int batchSize)
EventLog
instances will be loaded in a single
run. If not set, DEFAULT_BATCH_SIZE
will be used.

public void setQueryService(IQuery queryService)
public boolean hasNext()
count
is -1, then this batch has
ended (set in next()
) and false will be returned,
EventBacklog
will be ready to be switched over to an "adding"
state if empty, andcount
is also reset so further calls can
finish normally; otherwise query()
is called to load a new
eventLog
. Otherwise, just tests that field for null.
hasNext

instance which may be loaded by a call
to hasNext()
if necessary. If hasNext()
returns false,
a NoSuchElementException
will be thrown.

public abstract long more()
EventLog
instances are
available for processing. Some implementations may attempt to take extra
measures if the number is too large. Use 1 for a constant rather than
Long.MAX_VALUE
. Use 0 to stop execution.
public final ome.model.meta.EventLog nextEventLog(long id)
EventLog
with the next id after the given argument or
null if none exists. This method will only return "true" EventLog
instances, with a valid id. The excludes
list is used to filter
out unwanted EventLog
isntances.
public final ome.model.meta.EventLog lastEventLog()
public boolean addEventLog(Class<? extends ome.model.IObject> cls, long id)
EventLog
for the given Class
and id to the
backlog.
public void onApplicationEvent(org.springframework.context.ApplicationEvent arg0)
