METHODS

12       Beyond the methods documented below, this class inherits methods from
13       the RDF::Query::Algebra class.
14
15       "new ( $pattern, $opt_pattern )"
16           Returns a new Optional structure.
17
18       "construct_args"
19           Returns a list of arguments that, passed to this class'
20           constructor, will produce a clone of this algebra pattern.
21
22       "pattern"
23           Returns the base pattern (LHS) onto which the optional pattern
24           joins.
25
26       "optional"
27           Returns the optional pattern (RHS).
28
29       "sse"
30           Returns the SSE string for this algebra expression.
31
32       "as_sparql"
33           Returns the SPARQL string for this algebra expression.
34
35       "as_spin ( $model )"
36           Adds statements to the given model to represent this algebra object
37           in the SPARQL Inferencing Notation (<http://www.spinrdf.org/>).
38
39       "as_hash"
40           Returns the query as a nested set of plain data structures (no
41           objects).
42
43       "type"
44           Returns the type of this algebra expression.
45
46       "referenced_variables"
47           Returns a list of the variable names used in this algebra
48           expression.
49
50       "potentially_bound"
51           Returns a list of the variable names used in this algebra
52           expression that will bind values during execution.
53
54       "definite_variables"
55           Returns a list of the variable names that will be bound after
56           evaluating this algebra expression.
