Class LegacySortedDocValues


  • @Deprecated
    public abstract class LegacySortedDocValues
    extends LegacyBinaryDocValues
    Deprecated.
    Use SortedDocValues instead.
    A per-document byte[] with presorted values.

    Per-Document values in a SortedDocValues are deduplicated, dereferenced, and sorted into a dictionary of unique values. A pointer to the dictionary value (ordinal) can be retrieved for each document. Ordinals are dense and in increasing sorted order.

        protected LegacySortedDocValues()
        Deprecated.
        Sole constructor. (For invocation by subclass constructors, typically implicit.)

      • getOrd

        public abstract int getOrd​(int docID)
        Deprecated.
        Returns the ordinal for the specified docID.
        Parameters:
        docID - document ID to lookup
        Returns:
        ordinal for the document: this is dense, starts at 0, then increments by 1 for the next value in sorted order. Note that missing values are indicated by -1.
      • lookupOrd

        public abstract BytesRef lookupOrd​(int ord)
        Deprecated.
        Retrieves the value for the specified ordinal. The returned BytesRef may be re-used across calls to lookupOrd(int) so make sure to copy it if you want to keep it around.
        Parameters:
        ord - ordinal to lookup (must be >= 0 and < getValueCount())
        See Also:
        getOrd(int)
      • getValueCount

        public abstract int getValueCount()
        Deprecated.
        Returns the number of unique values.
        Returns:
        number of unique values in this SortedDocValues. This is also equivalent to one plus the maximum ordinal.
      • lookupTerm

        public int lookupTerm​(BytesRef key)
        Deprecated.
        If key exists, returns its ordinal, else returns -insertionPoint-1, like Arrays.binarySearch.
        Parameters:
        key - Key to look up
