Overview
Vendored Google Closure Library module providing a Hash Map data structure used by Selenium JavaScript atoms.
Description
goog.structs.Map is a vendored copy of the Google Closure Library module. It implements a Hash Map data structure suited for complex key types, backed by a plain JS object with a parallel keys array for efficient iteration. The class is deprecated in favor of ES6 Maps. It tracks a version number for detecting changes during iteration and maintains a size property. 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.
