Summary of the DOM structure

The following list displays the DOM structure in outline format. Numbers at the beginning of each line represent the level of an object. For example, an object preceded by "03" is a child of next highest "02" object, which, in turn, is a child of the next highest "01" object.

In some cases, an object is available by specifying a property of its parent object. For example, the document.timelines property contains an array of Timeline objects (see document.timelines and Timeline object). These properties are noted in the following outline.

Finally, some objects are subclasses of other objects, rather than being children of other objects. An object that is a subclass of another object has methods and/or properties of its own in addition to the methods and properties of the parent object (the superclass). Subclasses share the same level in the hierarchy as their superclass. For example, the Item object is a superclass of the BitmapItem object (see Item object and BitmapItem object). These relationships are illustrated in the following outline:
