Class OutputVisitor

java.lang.Object

org.ek9lang.compiler.backend.jvm.OutputVisitor

All Implemented Interfaces:

INodeVisitor

public final class OutputVisitor
extends Object
implements INodeVisitor

Enhanced visitor that uses specialized ASM generators to produce JVM bytecode for IR constructs. Implements visitor pattern with typed visit methods for each IR instruction type. Uses single responsibility principle with separate generators for each instruction type.

Method Details

setMethodContext

public void setMethodContext(AbstractAsmGenerator.MethodContext methodContext,
 org.objectweb.asm.MethodVisitor mv,
 boolean isConstructor)

Set method context for all generators before processing a method's instructions. Must be called before processing each method to ensure proper variable/label management.

Parameters:

methodContext - Shared context for variable and label maps

mv - Method visitor for this specific method

isConstructor - Whether we're processing a constructor

visit

public void visit()

Description copied from interface: INodeVisitor

Entry point for visitors.

Specified by:

visit in interface INodeVisitor

visit

public void visit(IRConstruct construct)

Specified by:

visit in interface INodeVisitor

visit

public void visit(MemoryInstr memoryInstr)

Typed visit method for MemoryInstr - delegates to specialized generator.

visit

public void visit(ScopeInstr scopeInstr)
