Class SimilarityCacheCalculator<T extends DataObject>

  • All Implemented Interfaces:
    ThreadPoolExecutorListener
    Direct Known Subclasses:
    NESTSimilarityCacheCalculator
    public class SimilarityCacheCalculator<T extends DataObject>
extends Object
implements ThreadPoolExecutorListener
    Multithreaded calculator to compute all pairwise similarities between data objects stored in a given pool. The computed similarities are stored in the given cache.

    Make sure that the similarity cache is thread safe!

    PLEASE NOTE THAT THIS CALCULATOR WILL CLEAR THE CACHE BEFORE STARTING THE COMPUTATIONS!
