Method Detail

getTupleQueryResultFormat

public final TupleQueryResultFormat getTupleQueryResultFormat()

Specified by:

getTupleQueryResultFormat in interface TupleQueryResultWriter

Overrides:

getTupleQueryResultFormat in class SPARQLResultsXMLWriter

acceptsFileFormat

public boolean acceptsFileFormat(org.eclipse.rdf4j.common.lang.FileFormat format)

getWriter

public Writer getWriter()

Specified by:

getWriter in interface org.eclipse.rdf4j.common.io.CharSink

setPrettyPrint

@Deprecated
public void setPrettyPrint(boolean prettyPrint)

Deprecated.

Use AbstractQueryResultWriter.getWriterConfig() .set(BasicWriterSettings.PRETTY_PRINT, prettyPrint) instead.

Enables/disables addition of indentation characters and newlines in the XML document. By default, pretty-printing is set to true. If set to false, no indentation and newlines are added to the XML document. This method has to be used before writing starts (that is, before QueryResultWriter.startDocument() is called).
