Description

LogicalTypeAnnotationVisitor inside LogicalTypeAnnotation is intended to be used by clients who would like to execute custom code which depends on the type of the logical type annotation. However, it is difficult to give back any result from the visitor, since both LogicalTypeAnnotation#accept, and LogicalTypeAnnotationVisitor has void return type.
