Overview

Vendored Google Closure Library module providing HTML tag name constants used by Selenium JavaScript atoms.

Description

goog.dom.TagName is a vendored copy of the Google Closure Library module. It defines the goog.dom.TagName class whose constants enumerate all HTML tag names specified in the W3C HTML 4.01 index of elements and the HTML5.1 specification. Each constant is a typed string backed by a template parameter mapping to the corresponding HTMLElement type (e.g., TagName.A maps to HTMLAnchorElement). Selenium uses this as part of its JavaScript atom infrastructure for browser automation commands.

Usage

This module is consumed internally by Selenium's JavaScript atoms build system. It is not imported directly by end users.
