METHODS

12       Beyond the methods documented below, this class inherits methods from
13       the RDF::Query::Algebra class.
14
15       "new ( $left, $right )"
16           Returns a new Union 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       "first"
23           Returns the first pattern (LHS) of the union.
24
25       "second"
26           Returns the second pattern (RHS) of the union.
27
28       "patterns"
29           Returns the two patterns belonging to the UNION pattern.
30
31       "sse"
32           Returns the SSE string for this algebra expression.
33
34       "as_sparql"
35           Returns the SPARQL string for this algebra expression.
36
37       "as_hash"
38           Returns the query as a nested set of plain data structures (no
39           objects).
40
41       "type"
42           Returns the type of this algebra expression.
43
44       "referenced_variables"
45           Returns a list of the variable names used in this algebra
46           expression.
47
48       "potentially_bound"
49           Returns a list of the variable names used in this algebra
50           expression that will bind values during execution.
51
52       "definite_variables"
53           Returns a list of the variable names that will be bound after
54           evaluating this algebra expression.
