Class CombineAllPossible2Combinations

  extended by org.callbackparams.combine.AbstractCombineStrategy
      extended by org.callbackparams.combine.CombineAllPossible2Combinations
All Implemented Interfaces:

public class CombineAllPossible2Combinations
extends AbstractCombineStrategy

A strategy that creates a collection of callback-records in which all possible combinations of two individual callback-parameters will be represented. The strategy also tries to accomplish this task while keeping the number of callback-records as low as possible. This works alright but there is no guarantee that the lowest number of callback-records is always found but it seems to work flawlessly when the ValuesCollection contains three arrays and OK when there are four or more arrays.
If there is some combinatory expert available out there than feel free to provide some optimized algorithms for this. The current algorithms are pretty hard to understand and to some extent they also rely on chance.

Method Detail


protected Collection combineInternal(ValuesCollection vc)
Description copied from class: AbstractCombineStrategy
This is the method to implement when implementing CombineStrategy by subclassing AbstractCombineStrategy. The advantage compared to overriding AbstractCombineStrategy.combine(ValuesCollection) is that maxCount-check and validation of configuration for AbstractCombineStrategy.setMaxCount(int) and AbstractCombineStrategy.setRandomSeed(long) will be taken care of by the super-class - relieving this method to administer combining exclusivly.
