AbstractReadonlydocumentA reference to the module:engine/view/document~ViewDocument object.
ReadonlyviewAn instance of the view controller.
The state of the observer. If it is disabled, no events will be fired.
Checks whether a given DOM event should be ignored (should not be turned into a synthetic view document event).
Currently, an event will be ignored only if its target or any of its ancestors has the data-cke-ignore-events attribute.
This attribute can be used inside the structures generated by
module:engine/view/downcastwriter~ViewDowncastWriter#createUIElement ViewDowncastWriter#createUIElement() to ignore events
fired within a UI that should be excluded from CKEditor 5's realms.
The DOM event target to check (usually an element, sometimes a text node and potentially sometimes a document, too).
Whether this event should be ignored by the observer.
Disables and destroys the observer, among others removes event listeners created by the observer.
Enables the observer. This method is called when the observer is registered to the module:engine/view/view~EditingView and after module:engine/view/view~EditingView#forceRender rendering (all observers are #disable disabled before rendering).
A typical use case for disabling observers is that mutation observers need to be disabled for the rendering. However, a child class may not need to be disabled, so it can implement an empty method.
AbstractobserveStarts observing given DOM element.
DOM element to observe.
The name of the related root element.

Abstract base observer class. Observers are classes which listen to DOM events, do the preliminary processing and fire events on the module:engine/view/document~ViewDocument objects. Observers can also add features to the view, for instance by updating its status or marking elements which need a refresh on DOM events.
