NAME

Class::Component::Recipe::Collection - Component Collection

ATTRIBUTES

(get_|set_)classes

The actual list of classes. Provides get_classes and set_classes. Has to be an ArrayRef and is empty by default.

get_original_isa

Contains the original content of the target classes @ISA arrays after it has been changed by install.

METHODS

install($target_class, $base_class)

Installs the list of classes and the $base_class in the $target_class. The $_between value is internal, so reinstall can pass the former @ISA contents.

_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.
