Method Details

getProperties

public Collection<Axiom<?>> getProperties(NamedResource individual,
 URI context,
 boolean includeInferred)
                                   throws Rdf4jDriverException

Description copied from interface: Properties

Loads property values for the specified individual.

This method essentially does the same as Connection.find(cz.cvut.kbss.ontodriver.descriptor.AxiomDescriptor). It is up to the OOM provider to decide which values are part of the object model and which are unmapped.

Specified by:

getProperties in interface Properties

Parameters:

individual - Individual for which property values should be loaded

context - Context from which to load the property values

includeInferred - Whether to included inferred knowledge

Returns:

Collection of axioms representing property values

Throws:

Rdf4jDriverException

addProperties

public void addProperties(NamedResource individual,
 URI context,
 Map<Assertion,Set<Value<?>>> properties)
                   throws OntoDriverException

Description copied from interface: Properties

Adds the specified property values into the ontology.

The property values are either URIs (in case of object properties) or data literals of the appropriate Java type.

Specified by:

addProperties in interface Properties

Parameters:

individual - Property subject

context - Context into which to store the property values

properties - The values to add

Throws:

OntoDriverException - When storage access error occurs

removeProperties

public void removeProperties(NamedResource individual,
 URI context,
 Map<Assertion,Set<Value<?>>> properties)
                      throws OntoDriverException

Description copied from interface: Properties

Removes the specified property values from the ontology.

The property values are either URIs (in case of object properties) or data literals of the appropriate Java type.

Specified by:

removeProperties in interface Properties

Parameters:

individual - Property subject

context - Context from which to remove the property values

properties - The values to remove

Throws:

OntoDriverException - When storage access error occurs
