Method Detail

prefix

public void prefix(String prefix,
                   String namespace)
            throws org.eclipse.rdf4j.query.QueryResultHandlerException

Throws:

org.eclipse.rdf4j.query.QueryResultHandlerException

transform

public TupleResultBuilder transform(String path,
                                    String xsl)
                             throws org.eclipse.rdf4j.query.QueryResultHandlerException

Throws:

start

public TupleResultBuilder start(String... variables)
                         throws org.eclipse.rdf4j.query.QueryResultHandlerException

This must be called before calling namedResult(String, Object) or result(Object...).

Parameters:

variables - one or more variable names

Returns:

this builder, for the convenience of chaining calls

Throws:

org.eclipse.rdf4j.query.QueryResultHandlerException

startBoolean

public TupleResultBuilder startBoolean()

variables

public TupleResultBuilder variables(String... names)
                             throws org.eclipse.rdf4j.query.QueryResultHandlerException

Throws:

org.eclipse.rdf4j.query.QueryResultHandlerException

link

public TupleResultBuilder link(List<String> url)
                        throws org.eclipse.rdf4j.query.QueryResultHandlerException

Throws:

org.eclipse.rdf4j.query.QueryResultHandlerException

bool

public TupleResultBuilder bool(boolean result)
                        throws org.eclipse.rdf4j.query.QueryResultHandlerException

Throws:

org.eclipse.rdf4j.query.QueryResultHandlerException

result

public TupleResultBuilder result(Object... result)
                          throws org.eclipse.rdf4j.query.QueryResultHandlerException

start(String...) must be called before using this method.

Parameters:

result - a single result, one value for each variable, in the same order as the variable names were provided

Returns:

this builder, for the convenience of chaining calls

Throws:

org.eclipse.rdf4j.query.QueryResultHandlerException

namedResult

public TupleResultBuilder namedResult(String name,
                                      Object result)
                               throws org.eclipse.rdf4j.query.QueryResultHandlerException

start(String...) must be called before using this method.

Parameters:

name - the variable name, from the set of provided variable names

result - the result value associated with the given variable name

Returns:

this builder, for the convenience of chaining calls

Throws:

org.eclipse.rdf4j.query.QueryResultHandlerException

end

public TupleResultBuilder end()
                       throws org.eclipse.rdf4j.query.QueryResultHandlerException

This must be called if start(String...) is used, after all results are generated using either namedResult(String, Object) or result(Object...).

This must not be called if bool(boolean) or endBoolean() have been called.

Returns:

This object, for chaining with other calls.

Throws:

org.eclipse.rdf4j.query.QueryResultHandlerException

endBoolean
