TabulatedValues

java.lang.Object

net.simplace.sim.components.util.helper.TabulatedValues<X,Y>

Type Parameters:: X - Type of X column values (Double, Integer or String); Y - Type of Y column values (Double, Integer or String)

public class TabulatedValues<X,Y> extends Object

Handles tabulated values (X and Y column) and returns for a x-value a y-value by using the table (lookup, interpolation etc.)

  public TabulatedValues(net.simplace.sim.util.FWSimVariable<X[]> tx, net.simplace.sim.util.FWSimVariable<Y[]> ty)
  
  Creates Tabulated Values from two array valued SimVariables
  
  Parameters:
  
  tx - SimVariable for x values
  
  ty - SimVariable for y values
Method Details
- getValueAt
  
  public Y getValueAt(X x)
  
  Returns for a value x a coresponding value y by using tabulated data. If X and Y columns are numeric, then y is interpolated (or extrapolated). If Y column is integer, then the interpolated value is rounded to integer too. If X column is numeric and Y column a String, then y is taken from the first row where x is equal or greater than the X-column value. If X column is a String, then a lookup is performed by returning the y value from the row where x is found. If x is not found, then null is returned.
  
  Parameters:
  
  x - x-value
  
  Returns:
  
  y-value coresponding to x-value
