Overview

Generated C++ code for the canonical Monster sample schema, demonstrating FlatBuffers code generation output.

Description

monster_generated.h is the C++ source generated by flatc from the Monster tutorial schema. It defines accessor classes such as Monster, Weapon, Vec3, and associated builder types. This file serves as a reference example of what flatc produces for C++ and is included in the vendored tree as part of the FlatBuffers samples.

Usage

Vendored dependency used internally by MNN for model serialization. Not directly imported by end users.
