public class RDFSource
extends WrapperDataset
implements Resource

A base class for RDF-based resource mapping.

This class can be used as a basis for object mapping with higher-level client applications.

protected static final RDF rdf

The RDF Factory instance.

Constructor Detail

RDFSource

protected RDFSource(URI identifier,
                    Dataset dataset)

Create a new RDF-bearing resource.

Subclasses should have the same constructor signature to work with the provided object mapping mechanism.

Parameters:

identifier - the resource identifier

dataset - the dataset corresponding to this resource, may be null

RDFSource

protected RDFSource(URI identifier,
                    RDFSyntax syntax,
                    Dataset dataset)

Create a new RDF-bearing resource.

Subclasses should have the same constructor signature to work with the provided object mapping mechanism.

Parameters:

identifier - the resource identifier

syntax - the original RDF syntax in use

dataset - the dataset corresponding to this resource, may be null

Method Detail

getIdentifier

public URI getIdentifier()

Description copied from interface: Resource

The resource identifier.

Specified by:

getIdentifier in interface Resource

Returns:

the identifier

getContentType

public String getContentType()

Description copied from interface: Resource

The content type of the resource.

Specified by:

getContentType in interface Resource

Returns:

the content type

getEntity

public InputStream getEntity()
                      throws IOException

Description copied from interface: Resource

The resource entity.

Specified by:

getEntity in interface Resource

Returns:

the resource entity

Throws:

IOException - in the case of an error when generating the entity

serialize

public void serialize(RDFSyntax syntax,
                      OutputStream out)
               throws IOException

Serialize this object with a defined RDF syntax.

Parameters:

syntax - the RDF syntax

out - the output stream

Throws:

IOException - in the case of an I/O error

validate

public ValidationResult validate()

Validate the dataset for this object.

Subclasses may override this method to perform validation on the provided dataset. By default, this method is a no-op.

Returns:

the validation result

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Dataset
