メソッドの詳細

shardId

public ShardId shardId()

Returns the shard id this index belongs to.

doWrapDirectoryReader

protected org.apache.lucene.index.DirectoryReader doWrapDirectoryReader(org.apache.lucene.index.DirectoryReader in)
                                                                 throws IOException

定義:

doWrapDirectoryReader クラス内 org.apache.lucene.index.FilterDirectoryReader

例外:

IOException

wrap

public static ElasticsearchDirectoryReader wrap(org.apache.lucene.index.DirectoryReader reader,
                                                ShardId shardId)
                                         throws IOException

Wraps the given reader in a ElasticsearchDirectoryReader as well as all it's sub-readers in ElasticsearchLeafReader to expose the given shard Id.

パラメータ:

reader - the reader to wrap

shardId - the shard ID to expose via the elasticsearch internal reader wrappers.

例外:

IOException

addReaderCloseListener

public static void addReaderCloseListener(org.apache.lucene.index.DirectoryReader reader,
                                          org.apache.lucene.index.IndexReader.ReaderClosedListener listener)

Adds the given listener to the provided directory reader. The reader must contain an ElasticsearchDirectoryReader in it's hierarchy otherwise we can't safely install the listener.

例外:

IllegalArgumentException - if the reader doesn't contain an ElasticsearchDirectoryReader in it's hierarchy

getElasticsearchDirectoryReader

public static ElasticsearchDirectoryReader getElasticsearchDirectoryReader(org.apache.lucene.index.DirectoryReader reader)

Tries to unwrap the given reader until the first ElasticsearchDirectoryReader instance is found or null if no instance is found;
