24 Role used to let a value object get the index or the element name of
25 $self or of a node above.
26
28 eval_function
29 Retrieve the index or the element name. Parameters are
30
31 ( function_name , [ up ])
32
33 function_name
34 "element" or "index"
35
36 up Optional parameter to indicate how many level to go up before
37 retrieving the index or element name. Each "-" is equivalent to a
38 call to "parent|Config::Model::Node/parent". Can be repeated dashes
39 (""-"", ""- -"", ...) or a dash with a multiplier (""-"", ""-2"",
40 ...). White spaces are ignored.
41
42 compute_string
43 Perform a similar function as "eval_function" using a string where
44 function names are extracted.
45
46 E.g. "compute_string('&element(-)')" calls
47 "eval_function('element','-')"
