- Method Detail
  - toOriginalType
```
public OriginalType toOriginalType()
```
    Description copied from class: LogicalTypeAnnotation
    
    Convert this logical type to old logical type representation in parquet-mr (if there's any). Those logical type implementations, which don't have a corresponding mapping should return null.
    API should be considered private
    
    Specified by:
    
    toOriginalType in class LogicalTypeAnnotation
    
    Returns:
    
    the OriginalType representation of the new logical type, or null if there's none
  - accept
```
public <T> Optional<T> accept(LogicalTypeAnnotation.LogicalTypeAnnotationVisitor<T> logicalTypeAnnotationVisitor)
```
    Description copied from class: LogicalTypeAnnotation
    
    Visits this logical type with the given visitor
    
    Specified by:
    
    accept in class LogicalTypeAnnotation
    
    Parameters:
    
    logicalTypeAnnotationVisitor - the visitor to visit this type
