    Answer an iterator over all of the classes that are declared to be sub-classes of this class. Each element of the iterator will be an OntClass.
    
    Returns:
    An iterator over the sub-classes of this class.

    OntProfileException - If the Profile.SUB_CLASS_OF() property is not supported in the current language profile.
  - listSubClasses
```
com.hp.hpl.jena.util.iterator.ExtendedIterator<OntClass> listSubClasses(boolean direct)
```
    Answer an iterator over the classes that are declared to be sub-classes of this class. Each element of the iterator will be an OntClass. The distinguishing extra parameter for this method is the flag direct that allows some selectivity over the classes that appear in the iterator. Consider the following scenario:
```
   :B rdfs:subClassOf :A.
   :C rdfs:subClassOf :A.
   :D rdfs:subClassof :C.
 
```
    (so A has two sub-classes, B and C, and C has sub-class D). In a raw model, with no inference support, listing the sub-classes of A will answer B and C. In an inferencing model, rdfs:subClassOf is known to be transitive, so the sub-classes iterator will include D. The direct sub-classes are those members of the closure of the subClassOf relation, restricted to classes that cannot be reached by a longer route, i.e. the ones that are directly adjacent to the given root. Thus, the direct sub-classes of A are B and C only, and not D - even in an inferencing graph. Note that this is not the same as the entailments from the raw graph. Suppose we add to this example: :D rdfs:subClassof :A. Now, in the raw graph, A has sub-class C. But the direct sub-classes of A remain B and C, since there is a longer path A-C-D that means that D is not a direct sub-class of A. The assertion in the raw graph that A has sub-class D is essentially redundant, since this can be inferred from the closure of the graph.
    
    Note: This is is a change from the behaviour of Jena 1, which took a parameter closed to compute the closure over transitivity and equivalence of sub-classes. The closure capability in Jena2 is determined by the inference engine that is wrapped with the ontology model. The direct parameter is provided to allow, for example, a level-by-level traversal of the class hierarchy, starting at some given root. Observe that in Jena 1, passing true will tend to increase the number of results returned; in Jena 2 passing true will tend to reduce the number of results.
    Parameters:
    direct - If true, only answer the directly adjacent classes in the sub-class relation: i.e. eliminate any class for which there is a longer route to reach that child under the sub-class relation.
    
    Returns:
    an iterator over the resources representing this class's sub-classes

  - listDeclaredProperties
```
com.hp.hpl.jena.util.iterator.ExtendedIterator<OntProperty> listDeclaredProperties(boolean direct)
```
    Return an iterator over the properties associated with a frame-like view of this class. This captures an intuitive notion of the properties of a class. This can be useful in presenting an ontology class in a user interface, for example by automatically constructing a form to instantiate instances of the class. The properties in the frame-like view of the class are determined by comparing the domain of properties in this class's OntModel with the class itself. See: Presenting RDF as frames for more details.
    
    Note that many cases of determining whether a property is associated with a class depends on RDFS or OWL reasoning. This method may therefore return complete results only in models that have an attached reasoner.
    
    Parameters:
    direct - If true, restrict the properties returned to those directly associated with this class. If false, the properties of super-classes of this class will not be listed among the declared properties of this class.
    
    Returns:
    An iteration of the properties that are associated with this class by their domain.
  - hasDeclaredProperty
```
boolean hasDeclaredProperty(Property p,
                          boolean direct)
```
    Return an iteration of the properties associated with a frame-like view of this class. This captures an informal notion of the properties of a class, by looking at the domains of the properties in this class's model, and matching them to this class. A full description of the frame-like view of a class may be found in: RDF frames how-to for full details.
    Note that many cases of determining whether a property is associated with a class depends on RDFS or OWL reasoning. This method may therefore return complete results only in models that have an attached reasoner. See the

  - dropIndividual
```
void dropIndividual(Resource individual)
```
    Remove the given individual from the set of instances that are members of this class. This is effectively equivalent to the Individual.removeOntClass(com.hp.hpl.jena.rdf.model.Resource) method, but invoked via the class resource rather than via the individual resource.
    
    Parameters:
    individual - A resource denoting an individual that is no longer to be a member of this class
  - isHierarchyRoot
```
boolean isHierarchyRoot()
```
    Answer true if this class is one of the roots of the local class hierarchy. This will be true if either (i) this class has owl:Thing as a direct super-class, or (ii) it has no declared super-classes (including anonymous class expressions).
    
    Returns:
    True if this class is the root of the class hierarchy in the model it is attached to

  - asIntersectionClass
```
IntersectionClass asIntersectionClass()
```
    Answer a view of this class as an intersection class

    ConversionException - if the class cannot be converted to an intersection class given the language profile and the current state of the underlying model.
  - asComplementClass
```
ComplementClass asComplementClass()
```
    Answer a view of this class as a complement class

    ConversionException - if the class cannot be converted to a complement class given the language profile and the current state of the underlying model.
  - asRestriction
```
Restriction asRestriction()
```
    Answer a view of this class as a restriction class expression
    
    Returns:
    This class, but viewed as a Restriction facet
    
    Throws:
    
    ConversionException - if the class cannot be converted to a restriction given the language profile and the current state of the underlying model.
  - isEnumeratedClass
```
boolean isEnumeratedClass()
```
    Answer true if this class is an enumerated class expression
    
    Returns:
    True if this is an enumerated class expression
  - isUnionClass
```
boolean isUnionClass()
```
    Answer true if this class is a union class expression

    True if this is a complement class expression
  - isRestriction
```
boolean isRestriction()
```
    Answer true if this class is a property restriction
    
    Returns:
    True if this is a restriction
