Method Details

onlyGoodQuality

protected boolean onlyGoodQuality()

Specified by:

onlyGoodQuality in class ValueScaler.AbstractDoubleScaler

scale

protected double scale(double v)

The equations are:

  --Linear--
   Xs = dS * (dRx/dR) + SL
   X = dR * (dSxs/dS) + RL

   --SQRT--
   Xs = SQRT(dS*(dRx/dR))+SL

   Where 'd'˜delta, S=scaled values, X=raw input value, Xs=scaled input value
   SL/RL = shared/raw low

   This function scales the incoming value, from "raw" to "scaled".
   Right now, everything coming in will be converted to a double before being worked on, then
   converted back to whatever it was.
 

Specified by:

scale in class ValueScaler.AbstractDoubleScaler

deScale

protected double deScale(double v)

The opposite of scale, returns a scaled value back to the raw value.

Specified by:

deScale in class ValueScaler.AbstractDoubleScaler
