| ReactorBaseImpl | | public class ReactorBaseImpl implements ReactorBase(Code) | | ReactorBaseImpl is the base class for instances of classes from the
RDFS/OWL schema generated by the code generator.
If a class inheriting from ReactorBaseImpl is instantiated, it represents an
instance of a class from an RDFS/OWL schema. The properties of this class
instance are stored in an RDF model using RDF2Go (via the static Bridge
object) as triples of the form: (this.instanceIdentifier, key, value).
Besides methods for putting, getting and removing properties, the Map Interface is also supported for handling of all properties of this
instance in one Map, backed by the actual RDF2Go model.
RDF Reactor uses the following naming:
resource - instance of an RDF schema class, identified by the
resource ID (an URI or BlankNode), almost 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
