|
* The ElementManager manages DOM element references and
|
|
|
|
* interactions with elements.
|
|
|
|
*
|
|
|
|
* A web element is an abstraction used to identify an element when it
|
|
|
|
* is transported across the protocol, between remote- and local ends.
|
|
|
|
*
|
|
|
|
* Each element has an associated web element reference (a UUID) that
|
|
|
|
* uniquely identifies the the element across all browsing contexts. The
|
|
|
|
* web element reference for every element representing the same element
|
|
|
|
* is the same.
|
|
|
|
*
|
|
|
|
* The element manager provides a mapping between web element references
|
|
|
|
* and DOM elements for each browsing context. It also provides
|
|
|
|
* functionality for looking up and retrieving elements.
