## DESCRIPTION

The RDF::Trine::Parser::LineProtocol class provides A line-based protocol for querying and updating triple/quad stores.

## METHODS

- "handle\_op ( $op, $handler, $lineno )"

  Handles the RDF::Trine::Parser::RDFPatch::Op operation object. For 'A'dd operations, the `$handler` callback is called with the RDF statement. Otherwise an exception is thrown.

- "parse\_line ( $line, $base )"

  Parses the Line Protocol string `$line` and returns the corresponding RDF::Trine::Parser::RDFPatch::Op object.

- "execute\_line ( $line, $model, $out )"

  Parses the Line Protocol string `$line` and executes the parsed operation using the supplied `$model`. If the operation returns results (in the case of a Query operation), they are printed to the `$out` file handle.
