    • InterpolationFunction

      public InterpolationFunction(double[] xvalues, double[] yvalues, javax.measure.Unit<T> xunits, javax.measure.Unit<R> yunits, int decimal)
      Create an interpolation function for a series of x and y values
      Parameters:
      xvalues - the x values
      yvalues - the y values
      xunits - the x units
      yunits - the y units
      decimal - number of decimal places . Use InterpolationFunction.decimalPlacesToPreventRounding to prevent rounding. Or use other constructor

      Specified by:
      configure in interface Configurable
      Throws:
      FactoryException - if there is an error in configuration e.g. required variable not set or cannot connect to device

    • reconfigure

      public void reconfigure() throws FactoryException
      Description copied from interface: Configurable
      Re-initialisation of values and states.

      Moved from Reconfigurable which has been deleted

      Specified by:
      reconfigure in interface Configurable
      Throws:
      FactoryException

    • isConfigured

      public boolean isConfigured()
      Description copied from interface: Configurable
      Checks to see if the object is already configured.
      Specified by:
      isConfigured in interface Configurable
      Returns:
      return true if configured false otherwise

    • isConfigureAtStartup

      public boolean isConfigureAtStartup()
      Description copied from interface: Configurable
