Method Detail

handleNamespace

public void handleNamespace(String prefix,
                            String uri)
                     throws QueryResultHandlerException

Description copied from interface: RDFHandler

Handles a namespace declaration/definition. A namespace declaration associates a (short) prefix string with the namespace's URI. The prefix for default namespaces, which do not have an associated prefix, are represented as empty strings.

Specified by:

handleNamespace in interface RDFHandler

Overrides:

handleNamespace in class AbstractRDFWriter

Parameters:

prefix - The prefix for the namespace, or an empty string in case of a default namespace.

uri - The URI that the prefix maps to.

Throws:

QueryResultHandlerException

getRDFFormat

public RDFFormat getRDFFormat()

Description copied from interface: RDFWriter

Gets the RDF format that this RDFWriter uses.

endRDF

public void endRDF()
            throws RDFHandlerException

Description copied from interface: RDFHandler

Signals the end of the RDF data. This method is called when all data has been reported.

Throws:

RDFHandlerException - If the RDF handler has encountered an unrecoverable error.

consumeStatement

public void consumeStatement(Statement st)
                      throws RDFHandlerException

Description copied from class: AbstractRDFWriter

Consume a statement. Extending classes must override this method instead of overriding AbstractRDFWriter.handleStatement(Statement) in order to benefit from automatic handling of RDF-star conversion or encoding.

Overrides:

consumeStatement in class AbstractRDFWriter

Parameters:

st - the statement to consume.

Throws:

RDFHandlerException

handleComment

public void handleComment(String comment)
                   throws RDFHandlerException

Description copied from interface: RDFHandler

Handles a comment.

Parameters:

comment - The comment.

Throws:

RDFHandlerException - If the RDF handler has encountered an unrecoverable error.
