Class ExternSourceGenerator

java.lang.Object
org.ek9lang.compiler.common.ExternSourceGenerator
public class ExternSourceGenerator extends Object
Facade that combines ANTLR parsing with the ExternSourceVisitor to generate extern representations of EK9 source files. This is a key component for incremental builds: unchanged modules can be represented as extern source, avoiding full recompilation.
