# JVM Object Generation

|
The JVM object generation phase is responsible for creating JVM-native objects
|
|
|
|
|
representing the parser AST from the rust-native AST. This is required to allow
|
|
|
|
|
the compiler and runtime to work with the AST.

# Overall Architecture
|
|
|
|
|
|
|
|
|
|
The JVM foreign function interface (FFI), named
|
|
|
|
|
[Java Native Interface](https://en.wikipedia.org/wiki/Java_Native_Interface)
|
|
|
|
|
(JNI), enables the Rust parser library to call and be called by the parser
|
|
|
|
|
library implemented in Scala.
|
|
|
|
|
|
|
|
|
|
Specifically, in our architecture, the JNI is used for:
|
|
|
|
|
|
|
|
|
|
- Invoking Rust parser methods from Scala.
|
|
|
|
|
- Invoking Scala AST constructors from Rust.
|
