Method Detail

### addClassListener

    void addClassListener(ClassListener listener)

  Adds a ClassListener to receive events about this RDFSClass.

  Parameters:
    `listener` - the ClassListener to add

### addSuperclass

    void addSuperclass(RDFSClass superclass)

  Adds a class to the rdfs:subClassOfs of this.

  Parameters:
    `superclass` -

### createClone

    RDFSClass createClone()

  Creates a copy of anonymous classes which contain a completely new expression tree. Named classes are NOT copied.

  Returns:
    a clone of this or the object itself for named classes

### createInstance

    RDFResource createInstance(String name)

  Creates a new instance of this class.

  Parameters:
    `name` - the name of the new instance or null for a default name
  Returns:
    a new instance of this

### getDependingClasses

    Collection getDependingClasses()

  Gets all OWLAnonymousClasses the life cycle of which depends on this. These are deleted when this is deleted.

  From existing usage, it appears that only the direct anonymous classes are required to be returned - these are then iterated over

  Returns:
    a Collection of OWLAnonymousClass instances

### getEquivalentClasses

    Collection getEquivalentClasses()

  Gets a Collection of all directly equivalent Clses of this. These are those direct superclasses that also have this as direct superclass.

  Returns:
    a Collection of Cls objects

### getImageIcon

    ImageIcon getImageIcon()

  Gets an ImageIcon displaying this. This is a harder version of `getIcon()` for use when an ImageIcon is required.

  Returns:
    the ImageIcon

### getInferredInstanceCount

    int getInferredInstanceCount()

  Gets the number of direct inferred instances of this class. This is equivalent to `getInferredInstances(false).size()` but could be optimized internally for better performance.

  Returns:
    the number of inferred instances
  See Also:
    `getInferredInstances(boolean)`

### getInferredInstances

    Collection getInferredInstances(boolean includingSubclasses)

  Gets all resources that have this as their inferred type. Optionally, it is possible to include subclasses of this into the search.

  Parameters:
    `includingSubclasses` - true to include instances of subclasses of this
  Returns:
    the inferred instances of this

### getInstanceCount

    int getInstanceCount(boolean includingSubclasses)

  Gets the number of instances of this, possibly including the instances of all subclasses.

  Parameters:
    `includingSubclasses` - true to also include the instances of the subclasses
  Returns:
    the number of instances of this

### getInstances

    Collection getInstances(boolean includingSubclasses)

  Gets the instances of this, possibly including the instances of all subclasses.

  Parameters:
    `includingSubclasses` - true to also get the instances of the subclasses
  Returns:
    the instances of this

### getNamedSubclasses

    Collection getNamedSubclasses()

  Gets a Collection of all direct subclasses that are not anonymous. (This is a convenience method for getNamedSubclasses(false))

  Returns:
    a Collection of Cls objects

### getNamedSubclasses

    Collection getNamedSubclasses(boolean transitive)

  Gets the named subclasses of this class.

  Parameters:
    `transitive` - true to include the descendent classes or false to only include the direct named subclasses
  Returns:
    a Collection of RDFSNamedClass objects.

### getNamedSuperclasses

    Collection getNamedSuperclasses()

  Gets a Collection of all direct superclasses that are not anonymous. (This is a convenience method for getNamedSuperclasses(false))

  Returns:
    a Collection of Cls objects

### getNamedSuperclasses

    Collection getNamedSuperclasses(boolean transitive)

  Gets the superclasses of this class.

  Parameters:
    `transitive` - true to include the ancestor classes or false to only include the direct named superclasses
  Returns:
    A Collection of RDFSNamedClass objects.

### getNestedBrowserText

    String getNestedBrowserText()

  Gets the browser text when this is embedded into a complex expression. This usually returns the browser key enclosed with round brackets.

  Returns:
    the nested browser text

### getNestedNamedClasses

    void getNestedNamedClasses(Set set)

  Gets all RDFSClses that are somewhere used in the expression below this. If this is an anonymous class, this traverses the expression tree to collect them. If this is already an RDFSNamedClass, it will return itself.

  Parameters:
    `set` - an (initially empty) Set that will contain the nested named classes

### getParsableExpression

    String getParsableExpression()

  Deprecated. not needed anymore

### getPureSuperclasses

    Collection getPureSuperclasses()

  Gets the subset of those direct superclasses which are not at the same time equivalent classes (or operands of equivalent intersection classes). Note that equivalent classes are superclasses of each other, so that in many cases you may want to use this method instead of `getSuperclasses(false)`.

  Returns:
    the direct superclasses

### getSubclassCount

    int getSubclassCount()

  Gets the number of (direct) subclasses of this.

  Returns:
    the number of classes with this as a rdfs:subClassOf value

### getSubclasses

    Collection getSubclasses(boolean transitive)

  Gets the subclasses of this, including the subclasses of the subclasses etc.

  Returns:
    the subclass values

### getSuperclassCount

    int getSuperclassCount()

  Gets the number of (direct) superclasses of this.

  Returns:
    the number of rdfs:subClassOf values

### getSuperclasses

    Collection getSuperclasses(boolean transitive)

  Gets the superclasses of this, optionally including the superclasses of the superclasses etc.

  Returns:
    the rdfs:subClassOf values

### getUnionDomainProperties

    Collection getUnionDomainProperties()

  Equivalent to `getUnionDomainProperties(false)`.

  Returns:
    the properties that have this in their (direct) domain

### getUnionDomainProperties

    Collection getUnionDomainProperties(boolean transitive)

  Gets those properties that have this in their domain, with union semantics. If the argument is true, then this will also consider those properties that have superclasses of this in their domain.

  Parameters:
    `transitive` - true to include superclasses
  Returns:
    a Collection of RDFProperty objects

### hasEquivalentClass

    boolean hasEquivalentClass(RDFSClass other)

  Checks whether this is a (direct) equivalent class of a given other Cls.

  Parameters:
    `other` - the Cls to compare with
  Returns:
    true if other is among the direct equivalent classes

### hasPropertyValueWithBrowserText

    boolean hasPropertyValueWithBrowserText(RDFProperty property,
                                            String browserText)

  For an object-valued property, checks whether one of the property values has a given browser text.

  Parameters:
    `property` - the property (must not have datatype literals as values)
    `browserText` - the browser text to compare to
  Returns:
    true if one of the values of the property matches

### isAnonymous

    boolean isAnonymous()

  Checks whether this is an anonymous class. All classes except for instances of OWLNamedClass are anonymous.

  Specified by:
    `isAnonymous` in interface `RDFResource`
  Returns:
    true if this is anonymous
  See Also:
    `OWLModel.isAnonymousResourceName(java.lang.String)`

### isMetaclass

    boolean isMetaclass()

  Checks whether this is a metaclass, i.e. whether it is a subclass of rdfs:Class.

  Returns:
    true if this is a metaclass

### isSubclassOf

    boolean isSubclassOf(RDFSClass superclass)

  Checks whether this is a (direct) subclass of a given class.

  Parameters:
    `superclass` - the superclass in question
  Returns:
    true if this has superclass among its rdfs:subClassOf values

### removeClassListener

    void removeClassListener(ClassListener listener)

  Removes a ClassListener to receive events about this RDFSClass.

  Parameters:
    `listener` - the ClassListener to remove

### removeSuperclass
