NAME
Class::Component::Recipe::Collection
ATTRIBUTES
classes
The actual list of classes. Provides get_classes and set_classes. Has to be an ArrayRef and is empty by default.
METHODS
install($target_class, $base_class)
Installs the list of classes and the $base_class in the $target_class.
_ensure_loaded_class($class)
Takes care that the passed class name is loaded.
push($class, [$force])
Pushes a class at the end of the list.
If the $class is already present in the list, this is a no-op and will return 0. This can be changed by specifying a positive value for $force, which will remove the existing element before pushing. If the list has been changed, a 1 is returned.
pop()
Returns and removes the last element of the list.
unshift($class, [$force])
Pushes a class at the beginning of the list.
If the class is already present, this will be a no-op and just return 0. If the $force value is set to a positive value, any existing value will be removed before the unshifting. If the list was changed, a 1 is returned.
shift()
Returns and removes the first element from the list.
insert($class, $position, [$force])
Inserts $class in the list at $position.
If the class already exists in the list, this is a no-op and will just return 0. If the <$force> value is set to a positive value any other mentioning of the class in the list will be removed first. If the list got changed a 1 is returned.
remove($class)
This removes the $class from the list. If $class is not even in the list, it returns 0, otherwise 1 if it really changed something.
replace($class, $replacement)
This will replace $class in the list with $replacement. The call will croak if the $class is not even in the list.
get_position_of($class)
Returns the position of the class in the list (zero based) or undef if it's not in there.
has_class($class)
This predicate returns true or false depending on the existance of $class in the list.
