Method Detail

writeTriple

void writeTriple(org.openrdf.model.Resource s,
                 org.openrdf.model.URI p,
                 org.openrdf.model.Value o,
                 org.openrdf.model.URI g)

Writes a triple. Parameters can be null, then the triple will be silently ignored.

Parameters:

s - subject

p - predicate

o - object

g - graph

writeTriple

void writeTriple(org.openrdf.model.Resource s,
                 org.openrdf.model.URI p,
                 org.openrdf.model.Value o)

Write a triple. Parameters can be null, then the triple will be silently ignored.

Parameters:

s - subject

p - predicate

o - object

writeNamespace

void writeNamespace(String prefix,
                    String uri)

Write a namespace.

Parameters:

prefix - the prefix of the namespace

uri - the long URI identifying the namespace

close

void close()

Close the result.

Extractors should close their results as soon as possible, but don't have to, the environment will close any remaining ones. Implementations should be robust against multiple close() invocations.

openSubResult

ExtractionResult openSubResult(ExtractionContext extractionContext)

Open a result nested in the current one.

Parameters:

extractionContext - the context to be used to open the sub result.

Returns:

the instance of the nested extraction result.
