Examples of it.unimi.dsi.mg4j.index.IndexReader.nextIterator()

it.unimi.dsi.mg4j.index.IndexReader.nextIterator()
Returns an {@link IndexIterator} on the term after the current one (optional operation).
Note that after creation there is no current term. Thus, the first call to this method will return an {@link IndexIterator} on the first term. As a consequence, repeatedcalls to this method provide a way to scan sequentially an index. @return the index iterator of the next term, or null if there are no more termsafter the current one.

      final IndexReader indexReader = index.getReader();
      long blockSize = total / blockSizeDivisor++; // The approximate size of a block
      IndexIterator indexIterator;
      
      for ( int i = k = 0; i < terms; i++ ) {
        indexIterator = indexReader.nextIterator();
        frequency = indexIterator.frequency();
        if ( ! index.hasPositions ) count += frequency; 
        for ( int j = frequency; j-- != 0; ) {
          indexIterator.nextDocument();
          if ( index.hasPositions ) count += indexIterator.count();
