Method Detail

startDocument

public void startDocument(org.openrdf.model.URI documentURI)
                   throws TripleHandlerException

Specified by:

startDocument in interface TripleHandler

Throws:

TripleHandlerException

openContext

public void openContext(ExtractionContext context)
                 throws TripleHandlerException

Description copied from interface: TripleHandler

Informs the handler that a new context has been established. Contexts are not guaranteed to receive any triples, so they might be closed without any triple.

Specified by:

openContext in interface TripleHandler

Throws:

TripleHandlerException

receiveTriple

public void receiveTriple(org.openrdf.model.Resource s,
                          org.openrdf.model.URI p,
                          org.openrdf.model.Value o,
                          org.openrdf.model.URI g,
                          ExtractionContext context)
                   throws TripleHandlerException

Description copied from interface: TripleHandler

Invoked with a currently open context, notifies the detection of a triple.

Specified by:

receiveTriple in interface TripleHandler

Parameters:

s - triple subject, cannot be null.

p - triple predicate, cannot be null.

o - triple object, cannot be null.

g - triple graph, can be null.

context - extraction context.

Throws:

TripleHandlerException

receiveNamespace

public void receiveNamespace(String prefix,
                             String uri,
                             ExtractionContext context)
                      throws TripleHandlerException

Description copied from interface: TripleHandler

Invoked with a currently open context, notifies the detection of a namespace.

Specified by:

receiveNamespace in interface TripleHandler

Parameters:

prefix - namespace prefix.

uri - namespace URI.

context - namespace context.

Throws:

TripleHandlerException

closeContext

public void closeContext(ExtractionContext context)

Description copied from interface: TripleHandler

Informs the handler that no more triples will come from a previously opened context. All contexts are guaranteed to be closed before the final close(). The document context for each document is guaranteed to be closed after all local contexts of that document.

Specified by:

endDocument in interface TripleHandler

Parameters:

documentURI - document URI.
