## Class CheckIndex.VerifyPointsVisitor

- java.lang.Object
- - org.apache.lucene.index.CheckIndex.VerifyPointsVisitor

- All Implemented Interfaces:
    PointValues.IntersectVisitor
  Enclosing class:
    CheckIndex

      public static class CheckIndex.VerifyPointsVisitor
      extends Object
      implements PointValues.IntersectVisitor

  Walks the entire N-dimensional points space, verifying that all points fall within the last cell's boundaries.
  NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `PointValues.Relation` | `compare(byte[] minPackedValue, byte[] maxPackedValue)` Called for non-leaf cells to test how the cell relates to the query, to determine how to further recurse down the tree.
    `long` | `getDocCountSeen()` Returns total number of unique docIDs in this BKD tree
    `long` | `getPointCountSeen()` Returns total number of points in this BKD tree
    `void` | `visit(int docID)` Called for all documents in a leaf cell that's fully contained by the query.
    `void` | `visit(int docID, byte[] packedValue)` Called for all documents in a leaf cell that crosses the query.

      Sole constructor
      Throws:
        `IOException`

  - ### Method Detail

    - #### getPointCountSeen

          public long getPointCountSeen()

      Returns total number of points in this BKD tree

    - #### getDocCountSeen

          public long getDocCountSeen()

      Returns total number of unique docIDs in this BKD tree

    - #### visit

          public void visit(int docID)

      Description copied from interface: `PointValues.IntersectVisitor`
      Called for all documents in a leaf cell that's fully contained by the query. The consumer should blindly accept the docID.
      Specified by:
        `visit` in interface `PointValues.IntersectVisitor`

    - #### visit

          public void visit(int docID,
                            byte[] packedValue)

      Description copied from interface: `PointValues.IntersectVisitor`
      Called for all documents in a leaf cell that crosses the query. The consumer should scrutinize the packedValue to decide whether to accept it. In the 1D case, values are visited in increasing order, and in the case of ties, in increasing docID order.
      Specified by:
        `visit` in interface `PointValues.IntersectVisitor`

    - #### compare

          public PointValues.Relation compare(byte[] minPackedValue,
                                              byte[] maxPackedValue)

      Description copied from interface: `PointValues.IntersectVisitor`
      Called for non-leaf cells to test how the cell relates to the query, to determine how to further recurse down the tree.
      Specified by:
        `compare` in interface `PointValues.IntersectVisitor`
