NAME¶
Config::Model::Role::ComputeFunction - compute &index or &element functions
VERSION¶
version 2.154
SYNOPSIS¶
$value->eval_function('index'); $value->eval_function('element'); $value->eval_function('index','-'); $value->eval_function('index','- -'); $value->eval_function('index','-3'); $value->compute_string('&element(-)') $value->compute_string('&index(- -)');
DESCRIPTION¶
Role used to let a value object get the index or the element name of $self or of a node above.
METHODS¶
eval_function¶
Retrieve the index or the element name. Parameters are
( function_name , [ up ])
- function_name
- "element" or "index"
- up
- Optional parameter to indicate how many level to go up before retrieving the index or element name. Each "-" is equivalent to a call to "parent|Config::Model::Node/parent". Can be repeated dashes (""-"", ""- -"", ...) or a dash with a multiplier (""-"", "-2", ...). White spaces are ignored.
compute_string¶
Perform a similar function as "eval_function" using a string where function names are extracted.
E.g. "compute_string('&element(-)')" calls "eval_function('element','-')"
