TIEHASH()METHODS
- clear_code
-
$obj->clear_code;Clears the value.
- code
-
my $value = $obj->code; $obj->code($value);A basic getter/setter method. If called without an argument, it returns the value. If called with a single argument, it sets the value.
- code_clear
-
$obj->code_clear;Clears the value.
- filter
-
If the input is an array reference, it passes each element to the code reference. The element will be in
$_. Returns the first element for which the code reference returns a true value.If the input is a single string, it just returns that string. This is semantically correct - if there is only one string, it has to be the first one as well.
