Method Detail

createIndexWriterConfig

protected IndexWriterConfig createIndexWriterConfig(IndexWriterConfig.OpenMode openMode)

Description copied from class: DirectoryTaxonomyWriter

Create the IndexWriterConfig that would be used for opening the internal index writer.
Extensions can configure the IndexWriter as they see fit, including setting a merge-scheduler, or deletion-policy, different RAM size etc.

NOTE: internal docids of the configured index must not be altered. For that, categories are never deleted from the taxonomy index. In addition, merge policy in effect must not merge none adjacent segments.

Overrides:

createIndexWriterConfig in class DirectoryTaxonomyWriter

Parameters:

openMode - see IndexWriterConfig.OpenMode

See Also:

DirectoryTaxonomyWriter.openIndexWriter(Directory, IndexWriterConfig)

openIndexWriter

protected IndexWriter openIndexWriter(Directory directory,
                          IndexWriterConfig config)
                               throws IOException

Description copied from class: DirectoryTaxonomyWriter

Open internal index writer, which contains the taxonomy data.

Extensions may provide their own IndexWriter implementation or instance.
NOTE: the instance this method returns will be closed upon calling to DirectoryTaxonomyWriter.close().
NOTE: the merge policy in effect must not merge none adjacent segments. See comment in DirectoryTaxonomyWriter.createIndexWriterConfig(IndexWriterConfig.OpenMode) for the logic behind this.

Overrides:

openIndexWriter in class DirectoryTaxonomyWriter

Parameters:

directory - the Directory on top of which an IndexWriter should be opened.

config - configuration for the internal index writer.

Throws:

IOException

See Also:

DirectoryTaxonomyWriter.createIndexWriterConfig(IndexWriterConfig.OpenMode)

getDeletionPolicy

public SnapshotDeletionPolicy getDeletionPolicy()

Returns the SnapshotDeletionPolicy used by the underlying IndexWriter.

getIndexWriter

public IndexWriter getIndexWriter()

Returns the IndexWriter used by this DirectoryTaxonomyWriter.
