Class BlockTermsReader
java.lang.Object
org.apache.lucene.index.Fields
org.apache.lucene.codecs.FieldsProducer
org.apache.lucene.codecs.blockterms.BlockTermsReader
- All Implemented Interfaces:
Closeable
,AutoCloseable
,Iterable<String>
Handles a terms dict, but decouples all details of doc/freqs/positions reading to an instance of
PostingsReaderBase
. This class is reusable for codecs that use a different format for
docs/freqs/positions (though codecs are also free to make their own terms dict impl).
This class also interacts with an instance of TermsIndexReaderBase
, to abstract away
the specific implementation of the terms dict index.
- WARNING: This API is experimental and might change in incompatible ways in the next release.
