NAME

6       AtteanX::Parser::SPARQL - SPARQL 1.1 Parser.

VERSION

9       This document describes AtteanX::Parser::SPARQL version 0.030.
10

SYNOPSIS

12        use AtteanX::Parser::SPARQL;
13        my $algbrea = AtteanX::Parser::SPARQL->parse($sparql, $base_uri);
14        # or:
15        my $parser     = AtteanX::Parser::SPARQL->new();
16        my ($algebra) = $parser->parse_list_from_bytes($sparql, $base_uri);
17
18        # or to allow parsing of SPARQL 1.1 Updates:
19
20        my $algbrea = AtteanX::Parser::SPARQL->parse_update($sparql, $base_uri);
21        # or:
22        my $parser = AtteanX::Parser::SPARQL->new(update => 1);
23        my ($algebra) = $parser->parse_list_from_bytes($sparql, $base_uri);
24

DESCRIPTION

26       This module implements a recursive-descent parser for SPARQL 1.1 using
27       the AtteanX::Parser::SPARQLLex tokenizer. Successful parsing results in
28       an object whose type is one of: Attean::Algebra::Query,
29       Attean::Algebra::Update, or Attean::Algebra::Sequence.
30

ROLES

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

METHODS

49       "parse ( $sparql )"
50           Parse the $sparql query string and return the resulting
51           Attean::API::Algebra object.
52
53       "parse_update ( $sparql )"
54           Parse the $sparql update string and return the resulting
55           Attean::API::Algebra object.
56
57       "parse_list_from_io( $fh )"
58       "parse_list_from_bytes( $bytes )"
59       "parse_nodes ( $string )"
60           Returns a list of Attean::API::Term or Attean::API::Variable
61           objects, parsed in SPARQL syntax from the supplied $string. Parsing
62           is ended either upon seeing a DOT, or reaching the end of the
63           string.
64
65       "error"
66           Returns the error encountered during the last parse.
67
68       "new_binary_expression ( $operator, @operands )"
69           Returns a new binary expression structure.
70
71       "new_function_expression ( $function, @operands )"
72           Returns a new function expression structure.
