NAME
RDF::Trine::Serializer::SparqlUpdate - SPARQL/U serialization of triples
SYNOPSIS
my $sparqlu = RDF::Trine::Serializer::SparqlUpdate->new;
$query = $sparqlu->serialize_to_string( $stmt, delete => $model );
$query = $sparqlu->serialize_to_string( undef, delete => $iter );
my $sparqlu_quad = RDF::Trine::Serializer->new('sparqlu', quad_semantics => 1 );
$query = $sparqlu_quad->insert( $model );DESCRIPTION

METHODS
Beyond the methods documented below, this class inherits methods from the RDF::Trine::Serializer class.
new( [quad_semantics => (0|1)] )
Returns a new SPARQL/Update serializer object.
If quad_semantics is set, contexts/graphs will be considered for INSERT and DELETE clauses. Otherwise, the serializer works on the union graph of the model.
serialize_to_string ( $data, %opts )
Coerces both $data and $opts{delete} to a model and calls serialize_model_to_string with those.
serialize_to_string ( $fh, $data, %opts )
Coerces both $data and $opts{delete} to a model and calls serialize_model_to_string with those and writes the resulting string to filehandle $fh.
serialize_model_to_string ( $model )
Serializes the $model to SPARQL/Update, returning the result as a string.
serialize_model_to_file ( $fh, $model )
Serializes the $model to SPARQL/Update, printing the results to the supplied filehandle <$fh>.
Alias for "serialize_to_file".
serialize_iterator_to_file ( $file, $iter )
Serializes the iterator to SPARQL/Update, printing the results to the supplied filehandle <$fh>.
Alias for "serialize_to_file".
serialize_iterator_to_string ( $iter )
Serializes the iterator to SPARQL/Update, returning the result as a string.
Alias for "serialize_to_string".
statement_as_string ( $st )
Serializes a statement to a SPARQL/Update INSERT DATA clause.
Alias for "serialize_to_string".
_serialize_data( $data )
Turns $data into a string of N-Triples.
_to_model( $data )
Turns $data into a RDF::Trine::Model.
_create_clause( $type, $data, [$graph] )
Creates a SPARQL/U 'INSERT' or 'DELETE' clause, depending on $type.
$data can be anything that "_serialize_data" can coerce to N-Triples.
If $graph is given, clauses take the form
INSERT DATA { GRAPH <$graph> { ... } };otherwise they act on the default graph, like so:
INSERT DATA { ... };SEE ALSO
