**Enterprise-Grade Performance for the JVM Ecosystem.** `oak-java` is a high-performance, incremental Java parser built on the Oak framework. Optimized for modern Java features and large-scale enterprise systems, it delivers the speed and accuracy needed for real-time developer tools.
## ✨ Core Features
- **⚡ Blazing Fast**: Built in Rust for sub-millisecond parsing, essential for real-time feedback in massive enterprise codebases.
- **🔄 Truly Incremental**: Re-parse only what changed. Ideal for massive Java projects and responsive IDE feedback.
- **🛡️ Industrial-Grade Fault Tolerance**: Gracefully handles syntax errors, providing precise diagnostics for Java code.
- **🌳 High-Fidelity AST**: Captures every detail of Java, including records, annotations, and trivia.
- **Full Java Support**: Comprehensive coverage of records, sealed classes, and modules.
- **IDE Ready**: Designed from the ground up for Language Server Protocol (LSP) and MCP integration.
- **Lossless Syntax**: Retains all source details, making it perfect for automated refactoring and formatting.
## 🏗️ Modern Architecture
Leveraging the **Green/Red Tree** pattern (similar to Roslyn and rust-analyzer):
1. **Efficient Immutability**: Share nodes across tree versions without expensive copies.
2. **Type-Safe API**: Easy traversal with strongly-typed nodes.
3. **Zero-Copy Trivia**: Efficiently manage comments and whitespace.
