    -parent_id parent_id  link

An item_ref refers to an item (existing or non-existing) in the content repository relative to some parent_id. The item might be either a folder or some kind of "page" (e.g. a file). An item_ref might be complex, i.e. consist of a path of simple_item_refs, separated by "/". An item_ref stops at the first unknown part in the path and returns item_id == 0 and the appropriate parent_id (and name etc.) for insertion.

Switches:

-use_package_path (optional, defaults to "false")
-use_site_wide_pages (optional, defaults to "false")
-normalize_name (optional, defaults to "true")

make_link (scripted, public)

 <instance of xowiki::Package> make_link \
    [ -with_entities with_entities ] [ -privilege privilege ] \
    [ -link link ] object [ method ] args [ args... ]

Creates conditionally a link for use in xowiki. When the generated link will be activated, the specified method of the object will be invoked. make_link checks in advance, whether the actual user has enough rights to invoke the method. If not, this method returns empty.

Switches:

-with_entities (optional, defaults to "0")
-privilege (optional)
When provided, the privilege can be "public" (do not check rights) or a privilege to be checked on the package_id and the current user. When this parameter is not specified, the policy is used to determine the rights to be checked.
-link (optional)
When this parameter is specified, is used used as base link for export_vars when applied on pages (or for packages as next segment under the package url). When not specified, the base url for pages is the current url, and for packages it is the package url.

Parameters:

object (required, object)
The object to which the link refers to. If it is a package_id it will base to the root_url of the package_id. If it is a page, it will base to the page_url

method (optional)
Which method to use. This will be appended as "m=method" to the url. Examples for methods:

view: To view and existing page

edit: To edit an existing page

revisions: To view the revisions of an existing page

args (required)
List of attributes to be append to the link. Every element can be an attribute name, or a "name value" pair. Behaves like export_vars.

Returns:
The link or empty

reparent (scripted, public)

 <instance of xowiki::Package> reparent -item_id item_id  \
    -new_parent_id new_parent_id  \
    [ -allowed_parent_types allowed_parent_types ]

Reparent a wiki page from one parent page to another one. The function changes the parent_id in cr_items, updates the cr-child-rels, and clears the caches. The function does not require the item to be instantiated. Limitations: The method does not perform permission checks (whether the actual user has rights to move the page to another parent folder), which should be implemented by the calling methods. Currently, the method does not perform cycle checks. It might be recommended to make sure the target parent is in the same package instance.

Switches:

-item_id (required, integer)
item_id of the item to be moved
-new_parent_id (required, integer)
item_id of the target parent
-allowed_parent_types (optional, defaults to "::xowiki::FormPage ::xowiki::Page")

Testcases:
No testcase defined.

 <instance of xowiki::Package> resolve_page \

www-delete (scripted, public)

 <instance of xowiki::Package> www-delete [ -item_id item_id ] \

This web-callable "delete" method does not require an instantiated object, while the class-specific delete methods in xowiki-procs need these. If a (broken) object can't be instantiated, it cannot be deleted. Therefore, we need this package level delete method. While the class specific methods are used from the application pages, the package_level method is used from the admin pages. If no "item_id", "name" or "return_url" are given, take it from the query parameters.

Switches:

-item_id (optional)
-name (optional)
-parent_id (optional)
-return_url (optional)
