Class ClassTaxonomyComputationFactory

java.lang.Object
  org.semanticweb.elk.reasoner.taxonomy.ClassTaxonomyComputationFactory

All Implemented Interfaces:

InputProcessorFactory<Collection<IndexedClass>,ClassTaxonomyComputationFactory.Engine>

public class ClassTaxonomyComputationFactory
extends Object
implements InputProcessorFactory<Collection<IndexedClass>,ClassTaxonomyComputationFactory.Engine>

The factory for engines that concurrently construct a Taxonomy. The jobs are submitted using the method ClassTaxonomyComputationFactory.Engine.submit(Collection), which require the computation of the Node for the input Collection of IndexedClass.

Constructor Detail

ClassTaxonomyComputationFactory

public ClassTaxonomyComputationFactory(SaturationState saturationState,
                                       int maxWorkers,
                                       UpdateableTaxonomy<ElkClass> 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

ClassTaxonomyComputationFactory

public ClassTaxonomyComputationFactory(SaturationState saturationState,
                                       int maxWorkers)

Create a new class taxonomy engine for the input ontology index.

Parameters:

saturationState - the saturation state of the reasoner

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