Interface HjCountEureka<T>

All Superinterfaces:

HjEureka<T,Void,List<T>>

All Known Implementing Classes:

HjCountEurekaImpl

public interface HjCountEureka<T>
extends HjEureka<T,Void,List<T>>

Another variant of a parallel search is where we wish to know the first $K$ results that match a query.

We wish to terminate the computation when at least $K$ of the asynchronous computations have completed successfully. A HjCountEureka is initialized with a count $K$ and is resolved after exactly $K$ eureka events have been triggered. A call to HjCountEureka.get() returns a list of values of maximum length $K$ instead of a single value. If none of the tasks triggered a eureka, then an empty list is returned. In general, a HjSearchEureka can be viewed as a HjCountEureka with a count of 1. * Instances are created using a factory method in the HJlib runtime, e.g., ModuleZ.newCountEureka(long, int)
