Class CalculationApple

java.lang.Object

      org.apache.cocoon.components.flow.apples.samples.CalculationApple

All Implemented Interfaces:

LogEnabled, AppleController

public class CalculationApple
extends AbstractLogEnabled
implements AppleController

CalculationApple shows an easy Apple example implementation for a Calculator.

It is explicitely designed to show the difference with flowscript by remembering the 'lookahead' information from the previous path that entered already the other data.

In other words this shows that Apples are not building a complete tree of continuations like flowscript is doing. But the initial argument of course was that some cases simply don't need it.
