public abstract class RangeFieldQuery extends Query
Query class for searching `RangeField` types by a defined `PointValues.Relation`.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

- ## Constructor Details

  - ### RangeFieldQuery

    protected RangeFieldQuery(String field, byte[] ranges, int numDims, RangeFieldQuery.QueryType queryType)
    Create a query for searching indexed ranges that match the provided relation.
    Parameters:
      `field` - field name. must not be null.
      `ranges` - encoded range values; this is done by the `RangeField` implementation
      `queryType` - the query relation

- ## Method Details

  - ### visit

    public void visit(QueryVisitor visitor)
    Description copied from class: `Query`
    Recurse through the query tree, visiting any child queries.
    Specified by:
      `visit` in class `Query`
    Parameters:
      `visitor` - a QueryVisitor to be called by each query in the tree

  - ### createWeight

    public final Weight createWeight(IndexSearcher searcher, ScoreMode scoreMode, float boost) throws IOException
    Description copied from class: `Query`
    Expert: Constructs an appropriate Weight implementation for this query.

    Only implemented by primitive queries, which re-write to themselves.

    Overrides:
      `createWeight` in class `Query`
    Parameters:
      `scoreMode` - How the produced scorers will be consumed.
      `boost` - The boost that is propagated by the parent queries.
    Throws:
      `IOException`

  - ### hashCode

    public int hashCode()
    Description copied from class: `Query`
    Override and implement query hash code properly in a subclass. This is required so that `QueryCache` works properly.
    Specified by:
      `hashCode` in class `Query`
    See Also:
      - `Query.equals(Object)`

  - ### equals

    public final boolean equals(Object o)
    Description copied from class: `Query`
    Override and implement query instance equivalence properly in a subclass. This is required so that `QueryCache` works properly.

    Typically a query will be equal to another only if it's an instance of the same class and its document-filtering properties are identical to those of the other instance. Utility methods are provided for certain repetitive code.

    Specified by:
      `equals` in class `Query`
    See Also:
      - `Query.sameClassAs(Object)`
      - `Query.classHash()`

  - ### equalsTo

    protected boolean equalsTo(RangeFieldQuery other)
    Check equality of two RangeFieldQuery objects

  - ### toString

    public String toString(String field)
    Description copied from class: `Query`
    Prints a query to a string, with `field` assumed to be the default field and omitted.
    Specified by:
      `toString` in class `Query`

  - ### toString

    protected abstract String toString(byte[] ranges, int dimension)
    Returns a string of a single value in a human-readable format for debugging. This is used by `Query.toString()`.
    Parameters:
      `ranges` - encoded ranges, never null
      `dimension` - dimension of the particular value
    Returns:
      human readable value for debugging
