RainJava API
Advanced Runtime Class Transformation Framework
A foundational library providing Mixin and Coremod interoperability layers, powered by enterprise-grade bytecode and compilation tools.
Overview
RainJava API establishes the critical infrastructure for runtime class transformation pipelines. It serves as a middleware bridge between dynamic compilation workflows and Minecraft's standard modification systems (Mixin & Coremod), ensuring bytecode-level compatibility without compromising game stability.
While designed as the prerequisite foundation for the upcoming RainJava ecosystem, this API functions independently as a robust toolkit for developers requiring deep class manipulation capabilities.
Embedded Libraries
This mod ships with zero-external-dependency versions of industry-standard tools:
Javassist — High-level bytecode manipulation library for runtime class engineering
ECJ (Eclipse Compiler for Java) — Full-featured Java compiler capable of runtime source-to-bytecode transformation
JavaParser — Abstract Syntax Tree (AST) analysis and code generation framework
These libraries are shaded and isolated to prevent conflicts with other mods.
Technical Scope
Transformation Bridge — Facilitates communication between runtime-generated class definitions and established bytecode modification frameworks
Mixin Compatibility Layer — Enables standardized injection patterns to recognize and process dynamically provisioned classes
Coremod Integration — Provides stable hooks for runtime class definitions to participate in Forge's transformation chain
Sandboxed Execution — Implements security boundaries for runtime code evaluation environments
For Modders
Install this API if you:
Plan to develop for or use the upcoming RainJava framework
Require embedded Javassist/ECJ/JavaParser without bundling them yourself
Need stable Mixin/Coremod interoperability for advanced bytecode operations
