Overview
Vendored Google Closure Library module providing a timer class abstraction above setInterval, used by Selenium JavaScript atoms.
Description
goog.Timer is a vendored copy of the Google Closure Library module. It provides a timer class that other classes and objects can listen on, serving as an abstraction above setInterval. It extends goog.events.EventTarget to dispatch tick events at configurable intervals, supports custom timer objects (for environments other than window), handles Firefox's early timer firing by rescheduling, and enforces a maximum timeout value to prevent 32-bit integer overflow. Selenium uses this as part of its JavaScript atom infrastructure.
Usage
This module is consumed internally by Selenium's JavaScript atoms build system. Not imported directly by end users.
