    • FloatBucketResultNode

      public FloatBucketResultNode(double from, double to)
      Create a bucket with the given limits
      Parameters:

  • Method Details

    • empty

      public boolean empty()
      Description copied from class: BucketResultNode
      Tell if this bucket has zero width. Indicates that is has no value and can be considered a NULL range. An empty range is used by the backend to represent hits that end in no buckets.
      Specified by:
      empty in class BucketResultNode
      Returns:
      If this bucket has zero width.

    • getFrom

      public double getFrom()
      Obtain the bucket start
      Returns:
      bucket start

    • getTo

      public double getTo()
      Obtain the bucket end
      Returns:
      bucket end

    • onGetClassId

    • onCmp

      protected int onCmp(ResultNode rhs)
      Description copied from class: ResultNode
      This method must be implemented by all subclasses of this to allow ordering of results. This method is used by the Cloneable implementation.
      Specified by:
      onCmp in class ResultNode
      Parameters:
      rhs - The other node to compare with.
      Returns:
      Comparable result.
