    * manage_copyObjects(self, ids=None, REQUEST=None, RESPONSE=None) Method from OFS.CopySupport.CopyContainer class. It places a reference to the objects identified by ids list inside the pasteboard.
    * manage_cutObjects(self, ids=None, REQUEST=None) Same as above.
    * manage_pasteObjects(self, cb_copy_data=None, REQUEST=None) Method from OFS.CopySupport.CopyContainer class. It pastes the object referenced by cb_copy_data, which has to be the result of either manage_copyObjects or manage_cutObjects.
    * manage_delObjects(self, ids=[], REQUEST=None) Method from CMFPlone.PloneFolder.BasePloneFolder class. It deletes all elements which id belongs to ids list.
    * editMetadata(self, obj, allowDiscussion=None, title=None, subject=None, description=None, contributors=None, effective_date=None, expiration_date=None, format=None, language=None, rights=None, **kwargs) Method defined in CMFPlone.PloneTool.PloneTool class.
    * invokeFactory(self, type_name, id, RESPONSE=None, args, *kw) type_name is the name of the content type target for creation. Please note that this id has to be the same as the one shown in the tool portal_types (but it might be different from the type name shown in Plone's user interface). id is the identifier (short name) of the new object: this name is used to later build the url.

    * refreshCatalog(self, clear=0) This methods reindexes all objects found inside self.

          o record objects' attributes

                + range: defines a search range over an index (optional, default: off). Possible values: min to search for object with larger values than the maximun of the values passed in query, max same as min but searching for smaller values than the minimun, and minmax which is a combination of the formers.
                + level: only for Path indixes. It specifies the directory level in which start the search (optional, default: 0).
