Overview

Vendored Google Closure Library module providing a Set data structure used by Selenium JavaScript atoms.

Description

goog.structs.Set is a vendored copy of the Google Closure Library module. It implements a set data structure with O(1) add and remove operations, supporting both primitive values and object references. It is backed by goog.structs.Map internally and implements both goog.structs.Collection and ES6 Iterable. The class is deprecated in favor of ES6 Sets. 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.
