An instance of the PageUpdater class serves as a controller-like object for creating and updating pages by creating a new revision, or null revision, of a page. Features included:
- It allows for edit conflict resolution by offering compare-and-swap (CAS) protection against concurrent updates that occur between the time grabParentRevision() is called and saveRevision() inserts a new revision.
- It allows for the creation and update of content slots other than the main one.
- It allows for updates to be associated with edit tags and other information.
The PageUpdater class can be instantiated with WikiPage::newPageUpdater() (don't use the PageUpdaterFactory class).
Public methods
- saveRevision() - either change an existing article or create a new one.
- grabParentRevision() - return the 'parent revision', i.e. the currently known page revision to serve as the parent of the revision or update so that compare-and-swap (CAS) operations can be run. Must be called after saveRevision().
- updateRevision() - update derived slots of an existing article, along with caches (but not RC).
- getNewRevision() - get the new revision created by saveRevision()
- preventChange() - prevents the creation of new revision.
- Checks, etc., related to saveRevision()
- wasCommitted() - check whether saveRevision() has been called on this instance.
- getStatus()
- wasSuccessful() - check if saveRevision() was successful.
- wasRevisionCreated() - check if saveRevision() created a revision.
- isUnchanged() - deprecated since 1.38 in favour of wasRevisionCreated()
- isNew() - check if saveRevision() was called and created a new page.
- isChange() - check if the prepared edit is a change compared to the previous revision.
