Modifier and Type	Method and Description
void	afterTransactionApplied(boolean someFailureHappened, boolean streaming) Invoked after all changes of a transaction are applied.

Constructor Detail

SharedIndexWorkspaceImpl

public SharedIndexWorkspaceImpl(DirectoryBasedIndexManager indexManager,
                        WorkerBuildContext context,
                        Properties cfg)

Method Detail

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 IndexWriter

streaming - if no immediate visibility of the change is required (hint for performance)

getIndexWriter

public 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 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
