  • Method Details

    • submitDatum

      void submitDatum(double d)
      Accepts a data value.
      Parameters:
      d - datum
    • createSpan

      Span createSpan()
      Returns an object characterising the range of data submitted so far. This should not be called while another thread might be calling submitDatum(double).
      Returns:
      span of accumulated data
    • add

      void add(Ranger other)
      Merges the contents of the supplied ranger into this one. The effect is as if all the results accumulated into other had been accumulated into this one. The effect on the supplied other is undefined.

      The supplied ranger is assumed to be compatible with this one, which probably means created in the same way. If not, some RuntimeException such as a ClassCastException may result.

      Parameters:
      other - compatible ranger instance
    • createCompatibleRanger

      Ranger createCompatibleRanger()
      Returns a Ranger instance that is compatible with this one. It has no content (does not copy any data from this one), but the two may be merged using the add(uk.ac.starlink.ttools.plot2.Ranger) method.
      Returns:
      new compatible ranger instance
