David Geiger commented on MAHOUT-1308:
--------------------------------------
Hi Sebastian,
thanks for commenting. I agree that it's not a major problem as one might as
well implement the interface {{CandidateItemsStrategy}} directly. The abstract
class *{{AbstractCandidateItemsStrategy}}*, however, provides a convenient
basis for strategies that also implement the
{{MostSimilarItemsCandidateItemsStrategy}} interface. The code can be easily
copied, but given that most other abstract classes in taste can be extended, I
believe that the restricted visibility might be unintentional.

> In order to implement a custom CandidateItemsStrategy, I'd like to extend
> {{AbstractCandidateItemsStrategy}}. This is not possible as the visibility
> modifier of {{doGetCandidateItems()}} is package default. Can it be extended
> to protected?
