Constructor Details

TriXWriter

public TriXWriter(OutputStream out)

Creates a new TriXWriter that will write to the supplied OutputStream.

Parameters:

out - The OutputStream to write the RDF/XML document to.

TriXWriter

public TriXWriter(Writer writer)

Creates a new TriXWriter that will write to the supplied Writer.

Parameters:

writer - The Writer to write the RDF/XML document to.

TriXWriter

protected TriXWriter(XMLWriter xmlWriter)

Method Details

getWriter

public Writer getWriter()

Description copied from interface: CharSink

get the Writer used by this CharSink.

Specified by:

getWriter in interface CharSink

Returns:

an Writer

getRDFFormat

public RDFFormat getRDFFormat()

Description copied from interface: RDFWriter

Gets the RDF format that this RDFWriter uses.

Specified by:

getRDFFormat in interface RDFWriter

startRDF

public void startRDF()
              throws RDFHandlerException

Description copied from interface: RDFHandler

Signals the start of the RDF data. This method is called before any data is reported.

Specified by:

startRDF in interface RDFHandler

Overrides:

startRDF in class AbstractRDFWriter

Throws:

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

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.

Specified by:

endRDF in interface RDFHandler

Throws:

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

handleNamespace

public void handleNamespace(String prefix,
 String name)

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.

name - The URI that the prefix maps to.

consumeStatement

protected void consumeStatement(Statement st)

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.

handleComment

public void handleComment(String comment)
                   throws RDFHandlerException

Description copied from interface: RDFHandler

Handles a comment.

Specified by:

handleComment in interface RDFHandler

Parameters:

comment - The comment.

Throws:

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