Examples with ReaderSlice org.apache.lucene.index.ReaderSlice used on opensource projects

Example 1 with ReaderSlice

use of org.apache.lucene.index.ReaderSlice in project lucene-solr by apache.

the class FieldsConsumer method merge.

/** Merges in the fields from the readers in 
   *  <code>mergeState</code>. The default implementation skips
   *  and maps around deleted documents, and calls {@link #write(Fields)}.
   *  Implementations can override this method for more sophisticated
   *  merging (bulk-byte copying, etc). */
public void merge(MergeState mergeState) throws IOException {
    final List<Fields> fields = new ArrayList<>();
    final List<ReaderSlice> slices = new ArrayList<>();
    int docBase = 0;
    for (int readerIndex = 0; readerIndex < mergeState.fieldsProducers.length; readerIndex++) {
        final FieldsProducer f = mergeState.fieldsProducers[readerIndex];
        final int maxDoc = mergeState.maxDocs[readerIndex];
        f.checkIntegrity();
        slices.add(new ReaderSlice(docBase, maxDoc, readerIndex));
        fields.add(f);

    }
    Fields mergedFields = new MappedMultiFields(mergeState, new MultiFields(fields.toArray(Fields.EMPTY_ARRAY), slices.toArray(ReaderSlice.EMPTY_ARRAY)));

Example 2 with ReaderSlice

use of org.apache.lucene.index.ReaderSlice in project neo4j by neo4j.

the class PartitionedUniquenessVerifier method termsForField.

            ReaderSlice readerSlice = new ReaderSlice(0, Math.toIntExact(leafTerms.size()), 0);
            terms.add(leafTerms);
            readerSlices.add(readerSlice);
        }
