    ProfileException - If the Profile.SUB_CLASS_OF() property is not supported in the current language profile.
  - listSubClasses
```
public 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 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 exmaple, a level-by-level traversal of the class hierarchy, starting at some given root.

  - listDeclaredProperties
```
public ExtendedIterator<OntProperty> listDeclaredProperties()
```
    Equivalent to calling listDeclaredProperties(boolean) with default value direct = false.
    
    Specified by:
    
    listDeclaredProperties in interface OntClass
  - listDeclaredProperties
```
public 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.
    
    Specified by:
    
    listDeclaredProperties in interface OntClass
    
    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.

    Specified by:
    
    hasDeclaredProperty in interface OntClass
    
    Parameters:
    
    p - A property to test
    
    direct - If true, only direct associations between classes and properties are considered
    
    Returns:
    
    True if p is one of the declared properties of this class
