Detailed Description
Provides convenience methods to handle RDFS data.
Interface based on Sesame's RdfSchemaSource. (Copyright (C) 2002-2006 Aduna BV, GNU LGPL License applies.)
- Warning:
- Backward inferencing has not been implemented yet. Thus, methods like subClassOf() return the same as directSubClassOf().

Member Function Documentation
Get all defined RDF/S classes.
- Returns:
- a StatementIterator that iterates over all statements in the model defining an RDF/S class.
Gets all direct subClassOf relations with a specific sub- and/or superclass. A class A is a direct subclass of class B if there is no class C such that A is a subclass of C and C is a subclass of B.
- Parameters:
-
| subClass | The subclass of the relations that should be returned, or an empty node if relations with any subclass should be returned. |
| superClass | The superclass of the relations that should be returned, or an empty node if relations with any superclass should be returned. |
- Returns:
- A StatementIterator containing statements of the form (subClass, rdfs:subClassOf, superClass).
Gets all direct subPropertyOf relations with a specific sub- and/or superproperty. A property A is a direct subproperty of property B if there is no property C such that A is a subproperty of C and C is a subproperty of B.
- Parameters:
-
| subProperty | The subproperty of the relations that should be returned, or an empty node if relations with any subproperty should be returned. |
| superProperty | The superproperty of the relations that should be returned, or an empty node if relations with any superproperty should be returned. |
- Returns:
- A StatementIterator containing statements of the form (subProperty, rdfs:subPropertyOf, superProperty).
Gets all direct type relations with a specific instance and/or class.
- Parameters:
-
| someClass | The instance of the relations that should be returned, or an empty node if relations with any instance should be returned. |
| someType | The class of the relations that should be returned, or an empty node if relations with any class should be returned. |
- Returns:
- A StatementIterator containing statements of the form (someClass, rdf:type, someType).
Gets all domain relations with a specific property and/or domain class.
- Parameters:
-
| prop | The property of the relations that should be returned, or an empty node if relations with any property should be returned. |
| domain | The domain of the relations that should be returned, or an empty node if relations with any domain should be returned. |
- Returns:
- A StatementIterator containing statements of the form (prop, rdfs:domain, domain).
Gets all defined properties.
- Returns:
- A StatementIterator containing statements of the form (someProperty, rdf:type, rdf:Property).
Gets all range relations with a specific property and/or range class.
- Parameters:
-
| prop | The property of the relations that should be returned, or an empty node if relations with any property should be returned. |
| range | The range of the relations that should be returned, or an empty node if relations with any range should be returned. |
- Returns:
- A StatementIterator containing statements of the form (prop, rdfs:range, range).
Gets all subClassOf relations with a specific sub- and/or superclass. Note that the subClassOf relation is reflexive: a class is implicitly always a subclass of itself.
Do not use this method if the Soprano backend supports inferencing. Use directSubClassOf instead which is much faster.
- Parameters:
-
| subClass | The subclass of the relations that should be returned, or an empty node if relations with any subclass should be returned. |
| superClass | The superclass of the relations that should be returned, or an emtpy node if relations with any superclass should be returned. |
- Returns:
- A StatementIterator containing all valid statements of the form (subClass, rdfs:subClassOf, superClass) including those calculated through direct inferencing.
Gets all subPropertyOf relations with a specific sub- and/or superproperty. Note that the subPropertyOf relation is reflexive: a property is implicitly always a subproperty of itself.
Do not use this method if the Soprano backend supports inferencing. Use directSubPropertyOf instead which is much faster.
- Parameters:
-
| subProperty | The subproperty of the relations that should be returned, or an empty node if relations with any subproperty should be returned. |
| superProperty | The superproperty of the relations that should be returned, or an empty node if relations with any superproperty should be returned. |
- Returns:
- A StatementIterator containing all valid statements of the form (subProperty, rdfs:subPropertyOf, superProperty) including those calculated through direct inferencing.
Gets all type relations with a specific instance and/or class.
Do not use this method if the Soprano backend supports inferencing. Use directType instead which is much faster.
- Parameters:
-
| someClass | The instance of the relations that should be returned, or an empty node if relations with any instance should be returned. |
| someType | The class of the relations that should be returned, or an empty node if relations with any class should be returned. |
- Returns:
- A StatementIterator containing all valid statements of the form (someClass, rdf:type, someType) including those calculated through direct inferencing.
bool Soprano::RdfSchemaModel::isClass |
( |
const Node & |
resource |
) |
const |

- Returns:
- true if resource is a property, false otherwise.
bool Soprano::RdfSchemaModel::isDirectSubClassOf |
( |
const Node & |
subClass, |
|
|
const Node & |
superClass | |
|
) |
| | const |
Checks whether one resource is a direct subclass of another.
- Parameters:
-
| subClass | A class. |
| superClass | A class. |
- Returns:
- true if subClass is a direct subclass of superClass, false otherwise.
bool Soprano::RdfSchemaModel::isDirectSubPropertyOf |
( |
const Node & |
subProperty, |
|
|
const Node & |
superProperty | |
|
) |
| | const |
Checks whether one resource is a direct subproperty of another.
- Parameters:
