Validating Haxe-Generated C++ Header Implementation in github-linguist/linguist

This test file examines the Haxe-generated C++ header implementation for a Main class. The test suite validates the proper generation of C++ class declarations and memory management structures from Haxe source code. It ensures correct class registration and dynamic allocation functionality.

Test Coverage Overview

The test coverage focuses on validating the Haxe-to-C++ code generation pipeline, specifically for class declarations and object instantiation patterns.

Key areas tested include:

Class declaration and inheritance structure
Memory allocation and constructor implementation
Dynamic object creation and static method declarations
RTTI (Runtime Type Information) implementation

Implementation Analysis

The testing approach verifies the generated C++ header structure against Haxe compiler specifications.

Key implementation patterns include:

HXCPP macro integration for class attributes
Dynamic allocation wrapper methods
Virtual table setup and static registration
Class ID and type system implementation

Technical Details

Testing infrastructure includes:

HXCPP runtime environment
C++ compiler compatibility verification
Header include guard validation
Class member accessibility testing

Best Practices Demonstrated

The test demonstrates robust header file organization and Haxe-to-C++ conversion practices.

Notable implementations include:

Proper include guard definition
Consistent memory management patterns
Clear class hierarchy structure
Standardized naming conventions
