NAME

6       RDF::Query::Algebra::Service - Algebra class for SERVICE (federation)
7       patterns

VERSION

10       This document describes RDF::Query::Algebra::Service version 2.918.
11

METHODS

13       Beyond the methods documented below, this class inherits methods from
14       the RDF::Query::Algebra class.
15
16       "new ( $endpoint, $pattern, $silent )"
17           Returns a new Service structure.
18
19       "construct_args"
20           Returns a list of arguments that, passed to this class'
21           constructor, will produce a clone of this algebra pattern.
22
23       "endpoint"
24           Returns the endpoint resource of the named graph expression.
25
26       "pattern"
27           Returns the graph pattern of the named graph expression.
28
29       "silent"
30           Returns true if the service operation is to ignore errors during
31           execution.
32
33       "lhs"
34           If the SERVCE operation uses a variable endpoint, then it is
35           considered a binary operator, executing the left-hand-side pattern
36           first, and using results from it to bind endpoint URL values to use
37           in SERVICE evaluation.
38
39       "sse"
40           Returns the SSE string for this algebra expression.
41
42       "as_sparql"
43           Returns the SPARQL string for this algebra expression.
44
45       "as_hash"
46           Returns the query as a nested set of plain data structures (no
47           objects).
48
49       "type"
50           Returns the type of this algebra expression.
51
52       "referenced_variables"
53           Returns a list of the variable names used in this algebra
54           expression.
55
56       "potentially_bound"
57           Returns a list of the variable names used in this algebra
58           expression that will bind values during execution.
59
60       "definite_variables"
61           Returns a list of the variable names that will be bound after
62           evaluating this algebra expression.
63
64       "qualify_uris ( \%namespaces, $base_uri )"
65           Returns a new algebra pattern where all referenced Resource nodes
66           representing QNames (ns:local) are qualified using the supplied
67           %namespaces.
