public SharedIndexWorkspaceImpl(DirectoryBasedIndexManager indexManager,
WorkerBuildContext context,
Properties cfg)
afterTransactionApplied
public void afterTransactionApplied(boolean someFailureHappened,
boolean streaming)
- Description copied from interface:
Workspace
- Invoked after all changes of a transaction are applied.
Must be invoked strictly once after every
Workspace.getIndexWriter()
in a finally block
as implementations might rely on counters to release the IndexWriter.
- Specified by:
afterTransactionApplied
in interface Workspace
- Specified by:
afterTransactionApplied
in class AbstractWorkspaceImpl
- Parameters:
someFailureHappened
- usually false, set to true if errors
where caught while using the IndexWriterstreaming
- if no immediate visibility of the change is required (hint for performance)
getIndexWriter
public org.apache.lucene.index.IndexWriter getIndexWriter()
- Description copied from interface:
Workspace
- Gets the IndexWriter, opening one if needed.
- Specified by:
getIndexWriter
in interface Workspace
- Overrides:
getIndexWriter
in class AbstractWorkspaceImpl
- Returns:
- a new IndexWriter or an already open one, or null if an error happened.
getIndexWriter
public org.apache.lucene.index.IndexWriter getIndexWriter(ErrorContextBuilder errorContextBuilder)
- Overrides:
getIndexWriter
in class AbstractWorkspaceImpl
flush
public void flush()
- Description copied from interface:
Workspace
- Makes sure eventually pending changes are made visible to IndexReaders.
notifyWorkApplied
public void notifyWorkApplied(LuceneWork work)
- Description copied from interface:
Workspace
- Some workspaces need this to determine for example the kind of flush operations which are safe
to apply. Generally used for statistics.
- Parameters:
work
- the LuceneWork which was just processed
