java.lang.Object

ortus.boxlang.compiler.javaboxpiler.Transpiler

ortus.boxlang.compiler.javaboxpiler.JavaTranspiler

All Implemented Interfaces:

ITranspiler

public class JavaTranspiler
extends Transpiler

BoxLang AST to Java AST transpiler The registry maps a AST node to the corresponding Transformer Java class instance. Each transformer implements the logic to convert the BoxLang AST nodes into Java AST nodes.
