DESCRIPTION

Instances of this class provides access to the packages list used by the Lab as caches.

METHODS

$diff->added

Returns a listref containing the keys of the elements that has been added.

Each element is a listref of keys; this list (when dereferenced) can be used with the manifest's get method to look up the item.

$diff->removed

Returns a listref containing the keys of the elements that has been removed.

Each element is a listref of keys; this list (when dereferenced) can be used with the manifest's get method to look up the item.

$diff->changed

Returns a listref containing the keys of the elements that has been changed.

Each element is a listref of keys; this list (when dereferenced) can be used with the manifest's get method to look up the item.

$diff->nlist

Returns the ``new'' manifest used to create this diff. Note the manifest is not copied and may have been changed since the diff has been created.

$diff->olist

Returns the ``orig'' manifest used to create this diff. Note the manifest is not copied and may have been changed since the diff has been created.
