E
- the type of elements represented in the Nodepublic interface Node<E extends OWLObject> extends Iterable<E>
Nodes
. Each node contains
entities that are equivalent to each other. A hierarchy contains a top
node, which is the ancestor of all nodes in the hierarchy, and a
bottom node In a class hierarchy, the nodes contain OWLClass
objects. The top node contains owl:Thing
(and any other named classes
that are equivalent to owl:Thing
). The bottom node contains
owl:Nothing
(and any other named classes that are equivalent to
owl:Nothing
- these classes are unsatisfiable In an object
property hierarchy, the nodes contain OWLObjectProperty
objects. The
top node contains owl:topObjectProperty
(and any other named object
properties that are equivalent to owl:topObjectProperty
). The bottom
node contains owl:bottomObjectProperty
(and any other named object
properties that are equivalent to owl:bottomObjectProperty
). OWLDataProperty
objects. The top node contains owl:topDataProperty
(and any other data
properties that are equivalent to owl:topDataProperty
). The bottom
node contains owl:bottomDataProperty
(and any other data properties
that are equivalent to owl:bottomDataProperty
). Node
. In this case
the top node contains owl:Thing
and the bottom node contains
owl:Nothing
because the nodes in the hierarchy are OWLClass
nodes. In this case, class G
is equivalent to owl:Thing
so it
appears as an entity in the top node. Similarly, class K
is
unsatisfiable, so it is equivalent to owl:Nothing
and therefore
appears in the bottom node containing owl:Nothing
