# Visitor Pattern Generator

Creates Visitor pattern infrastructure for operations on object structures without modifying classes.

## When to Use

| Scenario | Example |
|----------|---------|
| Operations on object structure | Calculate price/tax on order items |
| Adding operations without modification | Export visitors (JSON, XML, CSV) |
| Different operations on same elements | Validation, transformation, rendering |
| Double dispatch needed | Type-specific behavior without instanceof |
