ome.services.fulltext

Class FullTextThread

java.lang.Object

ome.services.util.ExecutionThread

ome.services.fulltext.FullTextThread

All Implemented Interfaces:

Runnable

public class FullTextThread
extends ExecutionThread

Library entry-point for indexing. Once the FullTextThread is properly initialized calling ExecutionThread.run() repeatedly and from multiple threads should be safe. For more control, use the EventLogLoader.more() method to test how often calls to ExecutionThread.run() should be made. See Main for examples. By default, the indexing will take place as "root".

Since:

3.0-Beta3

Modifier and Type	Method and Description
void	doRun() Passes the FullTextIndexer instance to Executor.Work#doWork(org.springframework.transaction.TransactionStatus, org.hibernate.Session, ome.system.ServiceFactory) between calls to DetailsFieldBridge.lock() and DetailsFieldBridge.unlock() in order to guarantee that no other FieldBridge can edit the property.

Method Detail

start

public void start()

Called by Spring on creation. Currently a no-op.

doRun

public void doRun()

Passes the FullTextIndexer instance to Executor.Work#doWork(org.springframework.transaction.TransactionStatus, org.hibernate.Session, ome.system.ServiceFactory) between calls to DetailsFieldBridge.lock() and DetailsFieldBridge.unlock() in order to guarantee that no other FieldBridge can edit the property. Therefore, only one indexer using this idiom can run at a time.

Specified by:

doRun in class ExecutionThread

stop

public void stop()

Called by Spring on destruction. Waits for the global lock on DetailsFieldBridge then marks this thread as inactive.
