NAME

6       RDF::Query::Expression - Class for Expr expressions
7

VERSION

9       This document describes RDF::Query::Expression version 2.918.
10

METHODS

12       "new ( $op, @operands )"
13           Returns a new Expr structure.
14
15       "construct_args"
16           Returns a list of arguments that, passed to this class'
17           constructor, will produce a clone of this algebra pattern.
18
19       "op"
20           Returns the operator of the expression.
21
22       "operands"
23           Returns a list of the operands of the expression.
24
25       "sse"
26           Returns the SSE string for this algebra expression.
27
28       "explain"
29           Returns a string serialization of the expression appropriate for
30           display on the command line. This method is primarily used by the
31           "explain" method of the subclasses of RDF::Query::Plan.
32
33       "as_hash"
34           Returns the expression as a nested set of plain data structures (no
35           objects).
36
37       "type"
38           Returns the type of this algebra expression.
39
40       "referenced_variables"
41           Returns a list of the variable names used in this algebra
42           expression.
43
44       "nonaggregated_referenced_variables"
45           Returns a list of the variable names used in this algebra
46           expression except those used as aliases for aggregate operations.
