Method Summary
 void close()
          Deprecated.  
 DocsEnum docs(FieldInfo fieldInfo, BlockTermState termState, Bits liveDocs, DocsEnum reuse, int flags)
          Deprecated. Must fully consume state, since after this call that TermState may be reused.
 DocsAndPositionsEnum docsAndPositions(FieldInfo fieldInfo, BlockTermState termState, Bits liveDocs, DocsAndPositionsEnum reuse, int flags)
          Deprecated. Must fully consume state, since after this call that TermState may be reused.
 void init(IndexInput termsIn)
          Deprecated. Performs any initialization, such as reading and verifying the header from the provided terms dictionary IndexInput.
 BlockTermState newTermState()
          Deprecated. Return a newly created empty TermState
 void nextTerm(FieldInfo fieldInfo, BlockTermState _termState)
          Deprecated. Actually decode metadata for next term
 void readTermsBlock(IndexInput termsIn, FieldInfo fieldInfo, BlockTermState _termState)
          Deprecated. Reads data for all terms in the next block; this method should merely load the byte[] blob but not decode, which is done in PostingsReaderBase.nextTerm(org.apache.lucene.index.FieldInfo, org.apache.lucene.codecs.BlockTermState).
