java.lang.Object
  org.semanticweb.elk.util.collections.chains.ModifiableLinkImpl<ModifiableLinkRule<BackwardLink>>
      org.semanticweb.elk.reasoner.saturation.conclusions.ForwardLink.ThisBackwardLinkRule

All Implemented Interfaces:

LinkRule<BackwardLink>, ModifiableLinkRule<BackwardLink>, Rule<BackwardLink>, Link<LinkRule<BackwardLink>>, ModifiableLink<ModifiableLinkRule<BackwardLink>>

Enclosing class:

ForwardLink

public static class ForwardLink.ThisBackwardLinkRule
extends ModifiableLinkImpl<ModifiableLinkRule<BackwardLink>>
implements ModifiableLinkRule<BackwardLink>

A type of ModifiableLinkRule created for ForwardLinks and stored in the Context where it is produced. There can be at most one rule of this type stored in every Context. The rule essentially indexes all ForwardLinks produced in this Context and applies inferences with every produced BackwardLink in this Context, such as computing implied role chains.
