create_form_fields_from_form_constraints (scripted, public)
```
 <instance of xowiki::Page> create_form_fields_from_form_constraints \
    [ -lookup ] form_constraints
```
Create form-fields from form constraints. When "-lookup" is specified, the code reuses existing form-field instead of recreating it. Since create_raw_form_field uses destroy_on_cleanup, we do not have to care here about destroying the objects.

Switches:

-lookup
(optional)

Parameters:
form_constraints

Returns:
potentially empty list of form-field objects

www-bulk-delete (scripted, public)
```
 <instance of xowiki::Page> www-bulk-delete

This web-callable method performs a bulk delete based on the object names provided by the form-variable "objects" and refresh then the caller page. This method is e.g. called by the folder-procs. By passing the "instantiate_p" one can decide whether each item should be instantiated (useful when the delete logic from the whole item ancestry is required), or if we will rely on the cheaper deletion at the package level. The default is false.

This web-callable method deletes a single revision of a Page, which is actually performed by the "delete_revision" method of the package, which is responsible for caching. Since we instantiate the Page based on the "revision_id" query parameter, it is sufficient to delete here just based on the current instance variable of the revision_id.

www-diff (scripted, public)

 <instance of xowiki::Page> www-diff

This web-callable method produces a "diff" of two pages based on the current page and the revision_id provided as query parameter by "compare_revision_id". We can choose here between the more fancy "::util::html_diff" and a plain text diff. The latter is used, when the query variable "plain_text_diff" is provided, or when the fancy diff raises an exception.

This web-callable method provides a listing of pages. When the query parameter "children" is used, it returns the children of this item via the "child-resources" includelet. Otherwise, when this method is called on any kind of Form, it returns the form instances via the "form-usages" includelet. Otherwise, when this method is called on any kind of folder pages, it returns the elements of this folder via the "child-resources" includelet. If the above fails, it redirects to the starting page.

 <instance of xowiki::Page> www-view [ content ]

This web-callable method is called when viewing wiki content. The method "view" is used primarily as web API call, when the xowiki page is viewed. It is not intended for e.g. embedded wiki pages (use includes), since it contains full framing, etc. In most cases, the argument "content" is not provided, and it is computed via the "render" method of the current object. It is as well possible to reuse the rendering logic of the method for other pages, where some HTML content is already computed, but it should be viewed exactly as in the page viewing cases.

Parameters:
content (optional)
