Class InstanceTaxonomyComputationFactory

java.lang.Object

org.semanticweb.elk.reasoner.taxonomy.InstanceTaxonomyComputationFactory

All Implemented Interfaces:

InputProcessorFactory<IndexedIndividual,InstanceTaxonomyComputationFactory.Engine>, Interrupter

public class InstanceTaxonomyComputationFactory
extends Object
implements InputProcessorFactory<IndexedIndividual,InstanceTaxonomyComputationFactory.Engine>

The factory for engines that concurrently construct an InstanceTaxonomy. The jobs are submitted using the method InstanceTaxonomyComputationFactory.Engine.submit(IndexedIndividual), which require the computation of the Node for the input IndexedIndividual.

Constructor Detail

InstanceTaxonomyComputationFactory

public InstanceTaxonomyComputationFactory(SaturationState saturationState,
                                  int maxWorkers,
                                  UpdateableInstanceTaxonomy<ElkClass,ElkNamedIndividual> partialTaxonomy)

Create a shared engine for the input ontology index and a partially pre-computed taxonomy object. The taxonomy is used to avoid computations that have been made before. For this to work, the taxonomy object must originate from an earlier run of this engine on the same ontology.

Parameters:

saturationState - the saturation state of the reasoner

maxWorkers - the maximum number of workers that can use this factory

partialTaxonomy - the (partially pre-computed) class taxonomy object to store results in
