Class RuleApplicationFactory.BaseEngine

java.lang.Object
  org.semanticweb.elk.reasoner.saturation.rules.RuleApplicationFactory.BaseEngine

All Implemented Interfaces:

RuleEngine, InputProcessor<IndexedClassExpression>

Direct Known Subclasses:

RuleApplicationFactory.DefaultEngine, RuleDeapplicationFactory.DeapplicationEngine

Enclosing class:

RuleApplicationFactory

public abstract class RuleApplicationFactory.BaseEngine
extends Object
implements InputProcessor<IndexedClassExpression>, RuleEngine

This engine has all the functionality for applying rules but needs to be extended if new contexts may need to be created

Constructor Detail

RuleApplicationFactory.BaseEngine

protected RuleApplicationFactory.BaseEngine(SaturationStatistics localStatistics)

Method Detail

process

public void process()

Specified by:

process in interface InputProcessor<IndexedClassExpression>

finish

public void finish()

Specified by:

finish in interface InputProcessor<IndexedClassExpression>

process

protected void process(Context context)

Process all scheduled items in the given context

Parameters:

context - the context in which to process the scheduled items

getUsedConclusionsCountingVisitor

protected ConclusionVisitor<Boolean> getUsedConclusionsCountingVisitor(ConclusionVisitor<Boolean> ruleProcessor)

Filters the ConclusionVisitor that applies inference rules to Conclusions by wrapping, if necessary, with the code producing statistics

Parameters:

ruleProcessor - the ConclusionVisitor to be wrapped

Returns:

the input ConclusionVisitor possibly wrapped with some code for producing statistics

getBaseConclusionProcessor

protected ConclusionVisitor<Boolean> getBaseConclusionProcessor(BasicSaturationStateWriter saturationStateWriter)

Returns the base ConclusionVisitor that performs processing of Conclusions within a Context. This can be further wrapped in some other code.

Parameters:

saturationStateWriter - the SaturationStateImpl.AbstractWriter using which one can produce new Conclusions in Context s

Returns:

the base ConclusionVisitor that performs processing of Conclusions within a Context

getConclusionProcessor

protected ConclusionVisitor<?> getConclusionProcessor(BasicSaturationStateWriter saturationStateWriter)

Returns the final ConclusionVisitor that is used by this RuleApplicationFactory.DefaultEngine for processing Conclusions within Contexts

Parameters:

saturationStateWriter - the SaturationStateImpl.AbstractWriter using which one can produce new Conclusions in Context s

Returns:

the final ConclusionVisitor that is used by this RuleApplicationFactory.DefaultEngine for processing Conclusions within Contexts

getDecompositionRuleApplicationVisitor

protected abstract DecompositionRuleApplicationVisitor getDecompositionRuleApplicationVisitor()

getSaturationStateWriter

protected abstract BasicSaturationStateWriter getSaturationStateWriter()
