Soprano::RdfSchemaModel Class Reference
#include <Soprano/RdfSchemaModel>
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().

| StatementIterator Soprano::RdfSchemaModel::directType | ( | const Node & | someClass, | |
| const Node & | someType | |||
| ) | const |
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).
| StatementIterator Soprano::RdfSchemaModel::domain | ( | const Node & | prop, | |
| const Node & | domain | |||
| ) | const |
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).
| bool Soprano::RdfSchemaModel::isClass | ( | const Node & | resource | ) | const |
Checks whether the supplied resource represents a class.
- Parameters:
-
resource The resource to check.
- Returns:
- true if resource is a class, 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:
-
subProperty A property. superProperty A property.
- Returns:
- true if subProperty is a direct subproperty of superProperty, false otherwise.
Checks whether one resource is a direct instance of another.
- Parameters:
-
someClass An instance. someType A class.
- Returns:
- true if someClass is a direct instance of someType, false otherwise.
| bool Soprano::RdfSchemaModel::isProperty | ( | const Node & | resource | ) | const |
Checks whether the supplied resource represents a property.
- Parameters:
-
resource The resource to check.
- Returns:
- true if resource is a property, false otherwise.
Checks whether one resource is a subclass of another.
Do not use this method if the Soprano backend supports inferencing. Use isDirectSubClassOf instead which is much faster.
- Parameters:
-
subClass A class. superClass A class.
- Returns:
- true if subClass is a subclass of superClass, false otherwise.
| bool Soprano::RdfSchemaModel::isSubPropertyOf | ( | const Node & | subProperty, | |
| const Node & | superProperty | |||
| ) | const |
Checks whether one resource is a subproperty of another.
Do not use this method if the Soprano backend supports inferencing. Use isDirectSubPropertyOf instead which is much faster.
- Parameters:
-
subProperty A property. superProperty A property.
- Returns:
- true if subProperty is a subproperty of superProperty, false otherwise.
Checks whether one resource is a instance of another.
Do not use this method if the Soprano backend supports inferencing. Use isDirectType instead which is much faster.
- Parameters:
-
someClass An instance. someType A class.
- Returns:
- true if someClass is an instance of someType, false otherwise.
| StatementIterator Soprano::RdfSchemaModel::properties | ( | ) | const |
Gets all defined properties.
- Returns:
- A StatementIterator containing statements of the form (someProperty, rdf:type, rdf:Property).
| StatementIterator Soprano::RdfSchemaModel::range | ( | const Node & | prop, | |
| const Node & | range | |||
| ) | const |
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.

| const Node & | superClass = Node() | |||
| ) | const |
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.
| StatementIterator Soprano::RdfSchemaModel::subPropertyOf | ( | const Node & | subProperty, | |
| const Node & | superProperty = Node() | |||
| ) | const |
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.
| StatementIterator Soprano::RdfSchemaModel::type | ( | const Node & | someClass, | |
| const Node & | someType | |||
| ) | const |
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.
