man AtteanX::Parser::SPARQL (3): SPARQL 1.1 Parser.

VERSION

This document describes AtteanX::Parser::SPARQL version 0.017.

SYNOPSIS

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);

DESCRIPTION

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.

ROLES

This class consumes Attean::API::Parser, Attean::API::AtOnceParser, and Attean::API::AbbreviatingParser.

METHODS

"parse ( $sparql )": Parse the $sparql query string and return the resulting Attean::API::Algebra object.
"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.
"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.
