Class FieldCalculator

java.lang.Object
  jabble.FieldCalculator

public class FieldCalculator
extends java.lang.Object

An object of this class is able to calculate a Field as a function of a set of other Fields. FieldCalculators allow to quickly add or remove calculation of Fields that are not critical for the stability of the solution, and might not even need to be calculated at every iteration.

Constructor Summary

FieldCalculator(java.lang.String fieldName, FunctionField function)
The new object will calculate the Field named fieldName according to the function given.

Method Summary

void	processPoint(Point point) Calculates the function at the given point and updates the value of the Field.
void	setupFields(java.util.List<Slice> slices) Sets up the appropriate data stracture so that the FieldCalculator will operate on the given list of slices.
