BlockTermsReader

class BlockTermsReader(indexReader: TermsIndexReaderBase, postingsReader: PostingsReaderBase, state: SegmentReadState) : 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.
