  • Method Details

    • ramBytesUsed

      public long ramBytesUsed()
      Description copied from interface: Accountable
      Return the memory usage of this object in bytes. Negative values are illegal.
      Specified by:
      ramBytesUsed in interface Accountable
    • toString

      public String toString()
      Overrides:
      toString in class Object
    • compare

      int compare(int ord, BytesRef other)
    • setSkips

      private void setSkips(int termOrd, byte[] termBytes)
    • finishSkips

      private void finishSkips()
    • saveSkip

      private void saveSkip(int ord, int backCount)
    • iterator

      public TermsEnum iterator()
      Description copied from class: Terms
      Returns an iterator that will step through all terms. This method will not return null.
      Specified by:
      iterator in class Terms
    • intersect

      public TermsEnum intersect(CompiledAutomaton compiled, BytesRef startTerm)
      Description copied from class: Terms
      Returns a TermsEnum that iterates over all terms and documents that are accepted by the provided CompiledAutomaton. If the startTerm is provided then the returned enum will only return terms > startTerm, but you still must call next() first to get to the first term. Note that the provided startTerm must be accepted by the automaton.

      This is an expert low-level API and will only work for NORMAL compiled automata. To handle any compiled automata you should instead use CompiledAutomaton.getTermsEnum(org.apache.lucene.index.Terms) instead.

      NOTE: the returned TermsEnum cannot seek.

      Overrides:
      intersect in class Terms
    • size

      public long size()
      Description copied from class: Terms
      Returns the number of terms for this field, or -1 if this measure isn't stored by the codec. Note that, just like other term measures, this measure does not take deleted documents into account.
      Specified by:
      size in class Terms
    • getSumTotalTermFreq

      public long getSumTotalTermFreq()
      Description copied from class: Terms
      Returns the sum of TermsEnum.totalTermFreq() for all terms in this field. Note that, just like other term measures, this measure does not take deleted documents into account.
      Specified by:
      getSumTotalTermFreq in class Terms
    • getSumDocFreq

      public long getSumDocFreq()
      Description copied from class: Terms
      Returns the sum of TermsEnum.docFreq() for all terms in this field. Note that, just like other term measures, this measure does not take deleted documents into account.
      Specified by:
      getSumDocFreq in class Terms
    • getDocCount

      public int getDocCount()
      Description copied from class: Terms
      Returns the number of documents that have at least one term for this field. Note that, just like other term measures, this measure does not take deleted documents into account.
      Specified by:
      getDocCount in class Terms
    • hasFreqs

      public boolean hasFreqs()
      Description copied from class: Terms
      Returns true if documents in this field store per-document term frequency (PostingsEnum.freq()).
      Specified by:
      hasFreqs in class Terms
    • hasOffsets

      public boolean hasOffsets()
      Description copied from class: Terms
      Returns true if documents in this field store offsets.
      Specified by:
      hasOffsets in class Terms
    • hasPositions

      public boolean hasPositions()
      Description copied from class: Terms
      Returns true if documents in this field store positions.
      Specified by:

    • hasPayloads

      public boolean hasPayloads()
      Description copied from class: Terms
      Returns true if documents in this field store payloads.
      Specified by:
      hasPayloads in class Terms
