Sorters API

+

+All sorters implement the {@link org.apache.lucene.index.sorter.Sorter} interface. +Each sorter implementation sorts the documents in a directory according to the values of a document component such as +StoredFields, DocValues, Payload etc`. The relevant component is evident from the name of the sorter class. +Most sorter classes are generic and take in a parameter T which defines the type of the component +according to which the sorting should be done. This type must be comparable. +For example we can have an integer DocValues sorter, a double DocValues sorters and so on. +In order to use a generic sorter the user must supply the sorter with a {@link org.apache.lucene.index.sorter.To} object. +that can extract an object of a comparable type T according to which the sorting will be done. + +For example, sorting a directory according to an integer DocValues field will be done as follow: +

+  int[] docValuesSort(Directory dir) throws IOException{
+    final DocValuesSorter<Integer> docValSorter = new DocValuesSorter<Integer>("someField", new To<BytesRef, Integer>() {
+
+      @Override
+      public Integer from(final BytesRef bytes) {
+        return DocValuesArraySource.asInt(bytes);
+      }
+    });
+    return docValSorter.oldToNew(dir);    
+  }
+
+Currently the following sorters are implemented: +
    +
  1. {@link org.apache.lucene.index.sorter.DocumentSorter}
    2. +
  2. {@link org.apache.lucene.index.sorter.DocValuesSorter}
    3. +
  3. {@link org.apache.lucene.index.sorter.PayloadSorter}
    4. +
  4. {@link org.apache.lucene.index.sorter.ReverseDocIdSorter}
    5. +
+In addition, once a sorter is defined, the utility class {@link org.apache.lucene.index.sorter.SorterUtil} supplies +a convenient interface to read documents from an input directory, sort them and add them to an output +directory according to their new order. +

+ +

Sorting classes

+

+A sorting class is a class that extends a previously existing index class +and allows the index to be accessed according to a permutation on its original order. +Each sorting class received in its constructor an instance of its superclass +and a permutation +that defines the new order of the index. A sorting class exposes the same interface as its superclass +although not all of the superclasses functionality is currently supported. +
+The following sorting classes are available: +

    +
  1. {@link org.apache.lucene.index.sorter.SortingDocsAndPositionsEnum}
    2. +
  2. {@link org.apache.lucene.index.sorter.SortingDocsEnum}
    3. +
  3. {@link org.apache.lucene.index.sorter.SortingDocValues}
    4. +
  4. {@link org.apache.lucene.index.sorter.SortingFields}
    5. +
  5. {@link org.apache.lucene.index.sorter.SortingIndexReader}
    6. +
  6. {@link org.apache.lucene.index.sorter.SortingSource}
    7. +
  7. {@link org.apache.lucene.index.sorter.SortingTermEnum}
    8. +
  8. {@link org.apache.lucene.index.sorter.SortingTerms}
    9. +
