| Bridge | | public class Bridge extends BridgeBase (Code) | | Runtime model for a java bean property
For all getters and setters (and all other accessors): - if the object
implements URIEntity it's mapped to rdf:Resource, - otherwise it's mapped to
rdf:Literal by calling "toString" IMPROVE: better Literal handling?
RDF Reactor uses the following naming:
resource - instance of an RDF schema class, identified by the
resource ID (an URI or BlankNode), allmost all statements about the resource
use the resource ID as the object
property - a property belongs to a resource, represented by the
predicate of a statement about a resource
value - value of a property of a resource, represented by the object
of the statement with the property as predicate and the resource ID as the
subject

| Method Summary | |
| public static boolean | addValue(Model model, Resource o, URI propertyURI, Object value)
Add a value to the property of an object after checking if the object
already had the property with the same value. | | public static boolean | containsInstance(Model model, URI classURI)
Check if the model contains an instance of the given RDFS/OWL schema
class. | | public static Iterator<? extends Object> | getSparqlSelectSingleVariable(Model m, Class returnType, String sparqlSelectQuery)
Use a SPARQL query on the model and wrap the result in a
SparlSingleVariableIterator, to ensure that only single elements are
included in the result. | | public static boolean | isInstanceOf(Model model, Resource instanceID, URI classURI)
Check if a resource is an instance of a given RDFS/OWL class. | | public static void | setAllValue(Model model, Resource subject, URI prop, Object[] o)
Set the value of a property from a resource after removing all existing
values of the property from that resource. | | public static void | setValue(Model model, Resource resourceObject, URI propertyURI, Object value)
| | public static Boolean | updateValue(Model model, Resource resourceIdentifier, URI propertyURI, Object _old, Object _new)
Update the value of a property from a resource. | | public static boolean | updateValue(Model model, BlankNode blankNode, URI propertyURI, Object _old, Object _new)
Update the value of a property from a resource. |
| addValue | | public static boolean addValue(Model model, Resource o, URI propertyURI, Object value) throws ModelRuntimeException(Code) | | Add a value to the property of an object after checking if the object
already had the property with the same value.
Parameters:
model - -the underlying RDF2Go model
Parameters:
o - -URI or BlankNode identifying the resource
Parameters:
propertyURI - -URI of the property
Parameters:
value - -value of the property true if value was already in the model |
| containsInstance | | public static boolean containsInstance(Model model, URI classURI)(Code) | | Check if the model contains an instance of the given RDFS/OWL schema
class. It is assumed that every instance of a class has an accompanying
triple of the form (instanceID, rdf:type, classURI) in the model.
Parameters:
model - -the underlying RDF2Go model
Parameters:
classURI - -URI of the RDFS/OWL schema class true if the model contains an instance of the class URI |
| getSparqlSelectSingleVariable | | public static Iterator<? extends Object> getSparqlSelectSingleVariable(Model m, Class returnType, String sparqlSelectQuery) throws ModelRuntimeException(Code) | | Use a SPARQL query on the model and wrap the result in a
SparlSingleVariableIterator, to ensure that only single elements are
included in the result. Assume 'x' as variable name.
Parameters:
m - -the underlying RDF2Go model
Parameters:
returnType - -the desired Java return type
Parameters:
sparqlSelectQuery - -the SPARQL query string SparqlSingleVariableIterator wrapper around the SPARQL queryresult
throws:
Exception - |
| isInstanceOf | | public static boolean isInstanceOf(Model model, Resource instanceID, URI classURI) throws ModelRuntimeException(Code) | | Check if a resource is an instance of a given RDFS/OWL class.
Parameters:
model - -the underlying RDF2Go model
Parameters:
instanceID - -URI or BlankNode of the instance
Parameters:
classURI - -URI of the RDFS/OWL class true if the model contains the triple (instanceID; rdf:type,classURI)
throws:
Exception - |
| setAllValue | | public static void setAllValue(Model model, Resource subject, URI prop, Object[] o) throws ModelRuntimeException(Code) | | Set the value of a property from a resource after removing all existing
values of the property from that resource.
Parameters:
model - -the underlying RDF2Go model
Parameters:
subject - -URI or BlankNode identifying the resource
Parameters:
prop - -URI of the property
Parameters:
o - -value of the property
throws:
Exception - |
| setValue | | public static void setValue(Model model, Resource resourceObject, URI propertyURI, Object value)(Code) | | Set the value(s) of a property of an object, after removing all values of
the property from the object
Parameters:
model - -the underlying RDF2Go model
Parameters:
resourceObject - -URI or BlankNode identifying the object
Parameters:
propertyURI - -URI of the resource
Parameters:
value - -value(s) of the property, may be an array
throws:
ModelRuntimeException - |
| updateValue | | public static Boolean updateValue(Model model, Resource resourceIdentifier, URI propertyURI, Object _old, Object _new) throws ModelRuntimeException(Code) | | Update the value of a property from a resource. (Remove old value, add
new value.)
Parameters:
model - -the underlying RDF2Go model
Parameters:
resourceIdentifier - -URI or BlankNode identifying the resource
Parameters:
propertyURI - -URI of the property
Parameters:
_old - -old value of the property
Parameters:
_new - -new value of the property true if the property really had the old value
throws:
Exception - |
| updateValue | | public static boolean updateValue(Model model, BlankNode blankNode, URI propertyURI, Object _old, Object _new) throws ModelRuntimeException(Code) | | Update the value of a property from a resource. (Remove old value, add
new value.)
Parameters:
model - -the underlying RDF2Go model
Parameters:
resourceIdentifier - -BlankNode identifying the resource
Parameters:
propertyURI - -URI of the property
Parameters:
_old - -old value of the property
Parameters:
_new - -new value of the property true if the property really had the old value
