public abstract class PostingsReaderBase extends Object implements Closeable, Accountable
PostingsEnum
and
PostingsEnum
instances. It provides an
IndexInput (termsIn) where this class may read any
previously stored data that it had written in its
corresponding PostingsWriterBase
at indexing
time.Modifier | Constructor and Description |
