Interface ModifiablePair<R>

Type Parameters:

R - the type of pair being modified

All Superinterfaces:

com.choicemaker.shared.api.CMPair<R>, Iterable<R>

All Known Subinterfaces:

SynthesizedPair<R>

All Known Implementing Classes:

DefaultModifiablePair, DefaultSynthesizedPair

public interface ModifiablePair<R>
extends com.choicemaker.shared.api.CMPair<R>

A template for the client in a visitor pattern. This class allows one to define a chain of processing operations on a pair:

 DefaultPair p = new DefaultPair(person1,person2);
 ModfiablePair mp = new ModifiableGeneratedPair0(p);
 List>> processors = ;
 for (PairModifier> processor : processors) {
   mp = mp.acceptModification(processor);
 }
 

Method Summary

ModifiablePair<R>	acceptModification(PairModifier<R,ModifiablePair<R>> modifier) Accepts modification by the specified pair modifier.
PairModifier.ModificationResult	getCurrentStatus() Returns the result of the last modification to this instance.
void	setCurrentStatus(PairModifier.ModificationResult currentStatus) Sets the result of the last modification to this instance.
