    • intersect

      public TermsEnum intersect(CompiledAutomaton compiled, BytesRef startTerm) throws IOException
      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
      Throws:
      IOException
    • iterator

      public TermsEnum iterator() throws IOException
      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
      Throws:
      IOException
    • size

      public long size() throws IOException
      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
      Throws:
      IOException
    • getSumTotalTermFreq

      public long getSumTotalTermFreq() throws IOException
      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
      Throws:
      IOException
    • getSumDocFreq

      public long getSumDocFreq() throws IOException
      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
      Throws:
      IOException
    • getDocCount

      public int getDocCount() throws IOException
      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
      Throws:
      IOException
    • 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:
      hasPositions in class Terms
    • hasPayloads

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

      public BytesRef getMin() throws IOException
      Description copied from class: Terms
      Returns the smallest term (in lexicographic order) in the field. Note that, just like other term measures, this measure does not take deleted documents into account. This returns null when there are no terms.
      Overrides:
      getMin in class Terms
      Throws:
      IOException
    • getMax

      public BytesRef getMax() throws IOException
      Description copied from class: Terms
      Returns the largest term (in lexicographic order) in the field. Note that, just like other term measures, this measure does not take deleted documents into account. This returns null when there are no terms.
      Overrides:
      getMax in class Terms
      Throws:
      IOException
