Class SingletoneInstanceTaxonomy<T extends ElkObject,I extends ElkObject,N extends OrphanTypeNode<T,I>>

java.lang.Object
  org.semanticweb.elk.reasoner.taxonomy.SingletoneTaxonomy<T,N>
      org.semanticweb.elk.reasoner.taxonomy.SingletoneInstanceTaxonomy<T,I,N>

Type Parameters:

T - the type of objects stored in this taxonomy

I - the type of instances of nodes of this taxonomy

N - the type of the node of this taxonomy

All Implemented Interfaces:

InstanceTaxonomy<T,I>, Taxonomy<T>

public class SingletoneInstanceTaxonomy<T extends ElkObject,I extends ElkObject,N extends OrphanTypeNode<T,I>>
extends SingletoneTaxonomy<T,N>
implements InstanceTaxonomy<T,I>

An InstanceTaxonomy consisting of a single TypeNode = top node = bottom node, which has a single InstanceNode. Typically, this is used to represent an inconsistent InstanceTaxonomy.
