Method Detail

startDocument

public void startDocument(org.eclipse.rdf4j.model.IRI documentIRI)
                   throws TripleHandlerException

Deprecated.

Description copied from class: TripleWriterHandler

Writers may override this method to handle a "startDocument" extraction event. The default implementation does nothing.

Specified by:

startDocument in interface TripleHandler

Overrides:

startDocument in class TripleWriterHandler

Parameters:

documentIRI - the name of the document that was started

Throws:

TripleHandlerException - if an error occurred while responding to a "startDocument" extraction event.

writeTriple

public void writeTriple(org.eclipse.rdf4j.model.Resource s,
                        org.eclipse.rdf4j.model.IRI p,
                        org.eclipse.rdf4j.model.Value o,
                        org.eclipse.rdf4j.model.Resource g)
                 throws TripleHandlerException

Deprecated.

Description copied from interface: TripleWriter

Writes a triple and, optionally, a graph resource name.

Specified by:

writeTriple in interface TripleWriter

Parameters:

s - the subject to write

p - the predicate to write

o - the object to write

g - the graph name to write, or null

Throws:

TripleHandlerException - if there is an error writing the triple

writeNamespace

public void writeNamespace(String prefix,
                           String uri)
                    throws TripleHandlerException

Deprecated.

Description copied from interface: TripleWriter

Writes a prefix-namespace mapping.
NOTE: this method should be called before writing out any triples. Calling this method after writing out a triple may result in the prefix-namespace mapping being ignored.

Specified by:

writeNamespace in interface TripleWriter

Parameters:

prefix - the namespace prefix

uri - the namespace uri

Throws:

TripleHandlerException - if there was an error writing out the prefix-namespace mapping

endDocument

public void endDocument(org.eclipse.rdf4j.model.IRI documentIRI)
                 throws TripleHandlerException

Deprecated.

Description copied from class: TripleWriterHandler

Writers may override this method to handle an "endDocument" extraction event. The default implementation does nothing.

Specified by:

endDocument in interface TripleHandler

Overrides:

endDocument in class TripleWriterHandler

Parameters:

documentIRI - the document IRI.

Throws:

TripleHandlerException - if an error occurred while responding to a "endDocument" extraction event.

           throws TripleHandlerException

Deprecated.

Description copied from interface: TripleHandler

Will be called last and exactly once.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface TripleWriter

Throws:

TripleHandlerException - if there is an error closing the TripleHandler implementation.

Returns:

the annotation flag value.

setAnnotated

public void setAnnotated(boolean f)

Deprecated.

Description copied from interface: FormatWriter

Sets the annotation flag.

Specified by:
