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
TODO

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 { ... };
