A document may have one or more "views" associated with it, e.g., a computed view on a document after applying a CSS stylesheet, or multiple presentations (e.g., HTML Frame) of the same document in a client. That is, a view is some alternate representation of, or a presentation of, and associated with, a source document.
A view may be static, reflecting the state of the document when the view was created, or dynamic, reflecting changes in the target document as they occur, subsequent to the view being created. This Level of the DOM specification makes no statement about these behaviors.
This section defines an
AbstractView interface which
provides a base interface from which all such views shall derive. It
defines an attribute which references the target document of the
AbstractView. The only semantics of the
defined here create an association between a view and its target document.
There are no subinterfaces of
AbstractView defined in the DOM
AbstractView is defined in and used in this Level
in two places:
DocumentViewthat has a default view attribute associated with it. This default view is typically dependent on the implementation (e.g., the browser frame rendering the document). The default view can be used in order to identify and/or associate a view with its target document (by testing object equality on the
AbstractViewor obtaining the
UIEventtypically occurs upon a view of a Document (e.g., a mouse click on a browser frame rendering a particular Document instance). A
AbstractViewassociated with it which identifies both the particular (implementation-dependent) view in which the event occurs, and the target document the
UIEventis related to.
The interfaces found within this section are not mandatory. A DOM
application can use the
hasFeature method of the
DOMImplementation interface to determine whether they
are supported or not. The feature string for all the interfaces listed in
this section is "Views".

Document objects in DOM implementations supporting DOM
