Class ExternSourceVisitor

All Implemented Interfaces:

org.antlr.v4.runtime.tree.ParseTreeVisitor<Void>, EK9Visitor<Void>

public class ExternSourceVisitor
extends EK9BaseVisitor<Void>

Visitor that walks an EK9 parse tree and emits an extern source representation. Declarations are preserved, method/operator bodies are stripped. This is the foundation for incremental builds: unchanged modules can be represented as extern source, avoiding full recompilation.
