Class ScopeInstrAsmGenerator

java.lang.Object

org.ek9lang.compiler.backend.jvm.AbstractAsmGenerator

org.ek9lang.compiler.backend.jvm.ScopeInstrAsmGenerator

All Implemented Interfaces:

Consumer<ScopeInstr>

final class ScopeInstrAsmGenerator
extends AbstractAsmGenerator
implements Consumer<ScopeInstr>

Specialized ASM generator for ScopeInstr processing. Handles SCOPE_ENTER, SCOPE_EXIT, and SCOPE_REGISTER operations.

While JVM doesn't need explicit scope management for memory (GC handles that), scopes are critical for: - LocalVariableTable generation (debug information) - Variable lifetime tracking for debuggers - Proper variable visibility in nested blocks (if/else/switch/for/try)
