AtteanX::Parser::SPARQL - SPARQL 1.1 Parser.
This document describes AtteanX::Parser::SPARQL version 0.020.
use AtteanX::Parser::SPARQL; my $algbrea = AtteanX::Parser::SPARQL->parse($sparql, $base_uri); # or: my $parser = AtteanX::Parser::SPARQL->new(); my ($algebra) = $parser->parse_list_from_bytes($sparql, $base_uri); # or to allow parsing of SPARQL 1.1 Updates: my $algbrea = AtteanX::Parser::SPARQL->parse_update($sparql, $base_uri); # or: my $parser = AtteanX::Parser::SPARQL->new(update => 1); my ($algebra) = $parser->parse_list_from_bytes($sparql, $base_uri);
This module implements a recursive-descent parser for SPARQL 1.1 using the AtteanX::Parser::SPARQLLex tokenizer. Successful parsing results in an object whose type is one of: Attean::Algebra::Query, Attean::Algebra::Update, or Attean::Algebra::Sequence.
This class consumes Attean::API::Parser, Attean::API::AtOnceParser, and Attean::API::AbbreviatingParser.

parse ( $sparql )
Parse the $sparql query string and return the resulting Attean::API::Algebra object.
$sparql
parse_update ( $sparql )
Parse the $sparql update string and return the resulting Attean::API::Algebra object.
parse_list_from_io( $fh )
parse_list_from_bytes( $bytes )
parse_nodes ( $string )
Returns a list of Attean::API::Term or Attean::API::Variable objects, parsed in SPARQL syntax from the supplied $string. Parsing is ended either upon seeing a DOT, or reaching the end of the string.
$string
error
Returns the error encountered during the last parse.
new_binary_expression ( $operator, @operands )
Returns a new binary expression structure.
new_function_expression ( $function, @operands )
Returns a new function expression structure.
