public class BlockTermsReader extends FieldsProducer
Handles a terms dict, but decouples all details of doc/freqs/positions reading to an instance ofPostingsReaderBase
. 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.
