## Class SpanPositionRangeQuery

- java.lang.Object
- - org.apache.lucene.search.Query
  - - org.apache.lucene.search.spans.SpanQuery
    - - org.apache.lucene.search.spans.SpanPositionCheckQuery
      - - org.apache.lucene.search.spans.SpanPositionRangeQuery

- All Implemented Interfaces:
    Cloneable
  Direct Known Subclasses:
    SpanFirstQuery

      public class SpanPositionRangeQuery
      extends SpanPositionCheckQuery

  Checks to see if the `SpanPositionCheckQuery.getMatch()` lies between a start and end position See `SpanFirstQuery` for a derivation that is optimized for the case where start position is 0.

          public SpanPositionRangeQuery(SpanQuery match,
                                        int start,

  - ### Method Detail

    - #### acceptPosition

          protected FilterSpans.AcceptStatus acceptPosition(Spans spans)
                                                     throws IOException

      Description copied from class: `SpanPositionCheckQuery`
      Implementing classes are required to return whether the current position is a match for the passed in "match" `SpanQuery`. This is only called if the underlying last `Spans.nextStartPosition()` for the match indicated a valid start position.
      Specified by:
        `acceptPosition` in class `SpanPositionCheckQuery`
      Parameters:
        `spans` - The `Spans` instance, positioned at the spot to check
      Returns:
        whether the match is accepted, rejected, or rejected and should move to the next doc.
      Throws:
        `IOException`
      See Also:
        `DocIdSetIterator.nextDoc()`

    - #### getStart

          public int getStart()

      Returns:
        The minimum position permitted in a match

    - #### getEnd

          public int getEnd()

      Returns:
        the maximum end position permitted in a match.

    - #### 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`

    - #### equals

          public boolean equals(Object o)

      Description copied from class: `SpanPositionCheckQuery`
      Returns true iff `other` is equal to this.
      Overrides:
        `equals` in class `SpanPositionCheckQuery`
      See Also:
        `Query.sameClassAs(Object)`, `Query.classHash()`

    - #### 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.
      Overrides:
        `hashCode` in class `SpanPositionCheckQuery`
      See Also:
        `Query.equals(Object)`
