Overview

Vendored amalgamated source for the JsonCpp JSON parsing library.

Description

Amalgamated (single-file) C++ source for JsonCpp, combining all implementation files into one compilation unit. Includes the JSON header via #include "json/json.h" and requires the JSON_IS_AMALGAMATION flag to be defined (set by the amalgamated header). Implements JSON parsing, value manipulation, and serialization. Licensed under MIT / Public Domain dual license (Baptiste Lepilleur and The JsonCpp Authors).

Usage

Compiled as part of the Selenium IE WebDriver native components to provide JSON handling for WebDriver protocol communication.
