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, Iterable<String>
public class BlockTermsReader
- extends FieldsProducer
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.
