Type Parameters:

R - result type

All Known Implementing Classes:

LogicalTypeDefaultVisitor, LogicalTypeDuplicator
```
@PublicEvolving
public interface LogicalTypeVisitor<R>
```
The visitor definition of LogicalType. The visitor transforms a logical type into instances of R.
Incomplete types such as the TypeInformationRawType or UnresolvedUserDefinedType are visited through the generic visit(LogicalType).
