Constructor Detail

DirectoryBuilderImpl

public DirectoryBuilderImpl(Cache<?,?> metadataCache,
                    Cache<?,?> chunksCache,
                    Cache<?,?> distLocksCache,

Method Detail

create

public org.apache.lucene.store.Directory create()

Description copied from interface: BuildContext

Creates a Directory instance

Specified by:

create in interface BuildContext

Returns:

the new Directory

See Also:

Directory

chunkSize

public BuildContext chunkSize(int bytes)

Description copied from interface: BuildContext

Sets the chunkSize option for the Directory being created.

Specified by:

chunkSize in interface BuildContext

Parameters:

bytes - segments are fragmented in chunkSize bytes; larger values are more efficient for searching but less for distribution and network replication

Returns:

the same building context to eventually create the Directory instance

overrideSegmentReadLocker

public BuildContext overrideSegmentReadLocker(SegmentReadLocker srl)

Description copied from interface: BuildContext

Overrides the default SegmentReadLocker. In some cases you might be able to provide more efficient implementations than the default one by controlling the IndexReader's lifecycle

Specified by:

overrideSegmentReadLocker in interface BuildContext

Parameters:

srl - the new read locking strategy for fragmented segments

Returns:

the same building context to eventually create the Directory instance

See Also:

org.infinispan.lucene.readlocks

overrideWriteLocker

public BuildContext overrideWriteLocker(org.apache.lucene.store.LockFactory lockFactory)

Description copied from interface: BuildContext

Overrides the IndexWriter LockFactory

Specified by:

overrideWriteLocker in interface BuildContext

Parameters:

lockFactory - the LockFactory to be used by IndexWriters.

Returns:

the same building context to eventually create the Directory instance
