DESCRIPTION

24       Role used to let a value object get the index or the element name of
25       $self or of a node above.
26

METHODS

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','-')"
