Examples of com.hp.hpl.jena.rdf.model.Resource

com.hp.hpl.jena.rdf.model.Resource
An RDF Resource. Resource instances when created may be associated with a specific model. Resources created by a model will refer to that model, and support a range of methods, such as getProperty() and addProperty() which will access or modify that model. This enables the programmer to write code in a compact and easy style.
Resources created by ResourceFactory will not refer to any model, and will not permit operations which require a model. Such resources are useful as general constants.
This interface provides methods supporting typed literals. This means that methods are provided which will translate a built in type, or an object to an RDF Literal. This translation is done by invoking the toString() method of the object, or its built in equivalent. The reverse translation is also supported. This is built in for built in types. Factory objects, provided by the application, are used for application objects.

This interface provides methods for supporting enhanced resources. An enhanced resource is a resource to which the application has added behaviour. RDF containers are examples of enhanced resources built in to this package. Enhanced resources are supported by encapsulating a resource created by an implementation in another class which adds the extra behaviour. Factory objects are used to construct such enhanced resources.
