Class EnumIteratorImplInstr

org.ek9lang.compiler.ir.instructions.EnumIteratorImplInstr

All Implemented Interfaces:

INode

public final class EnumIteratorImplInstr
extends IRInstr

High-level IR instruction for generating enum iterator implementation.

This instruction abstracts the creation of a concrete iterator class for enumerations. Instead of generating detailed IR instructions for List creation, element addition, etc., this instruction tells the backend to generate an efficient iterator implementation appropriate for the target.

The backend is responsible for:

• Generating public static fields for each enum value on the enum class
• Initializing them in the class initializer with correct _ordinal and _name
• Generating an anonymous iterator class extending the parameterized Iterator type
• Implementing hasNext(), next(), and _isSet() methods
• Returning an instance of this anonymous iterator

JVM backend generates an anonymous inner class with static field references. LLVM backend generates struct + functions + static data section.
