Method Detail

end

public void end()

Signals the writing process is completed. The underlying InputStream is *not* closed, but the caller should not call additional methods on this writer as that will normally yield syntax errors in the output.

Specified by:

end in interface RDFHandler

Specified by:

end in interface RDFWriter

start

public void start()

Signals that the RDF writing process is starting.

Specified by:

start in interface RDFHandler

Specified by:

start in interface RDFWriter

namespace

public void namespace(@Nonnull
                      java.lang.String thePrefix,
                      @Nonnull
                      java.lang.String theIRI)

Provide a namespace to the writer. This method can be called before writing has started, in which case, the namespace bindings are buffered and written when appropriate after writing has begun.

Specified by:

namespace in interface RDFHandler

Specified by:

namespace in interface RDFWriter

Parameters:

thePrefix - the namespace prefix

theIRI - the associated IRI

comment

public void comment(@Nonnull
                    java.lang.String theComment)

Write a comment to the output. Writing need not be started at this point; comments can be written prior to any actual serialized RDF

Specified by:

comment in interface RDFWriter

Parameters:

theComment - the comment to write

handle

public void handle(@Nonnull
                   Statement theStmt)

Write the given Statement

Specified by:

handle in interface RDFHandler

Specified by:

handle in interface RDFWriter

Parameters:

theStmt - the statement to write

format

@Nonnull
public RDFFormat format()

The format this writer will serialize output in.

Specified by:

format in interface RDFWriter

Returns:

the format
