BasicColumnMapper (Digipost Digg 0.32 API)

Type Parameters:

R - The type of the result.

All Superinterfaces:

ColumnMapper<R>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface BasicColumnMapper<R>
extends ColumnMapper<R>
```
The basic ColumnMapper retrieves a value from a ResultSet, and offers a way to compose a chain of functions that maps the value. As the value retrieved from the ResultSet is unconditionally passed down the chain of mapping functions, if retrieving a value from a nullable column, consider using a NullableColumnMapper instead.

    Create a new BasicColumnMapper which will map the result of this one using the given function.
    
    Type Parameters:
    
    S - The type of object the new ColumnMapper yields from a ResultSet
    
    Parameters:
    
    mapper - the mapping function
    
    Returns:
    
    the new mapper

default BasicColumnMapper<R> nullFallthrough()
```
    Specify that a retrieved null value will short circuit any chain from this point. A mapping chain can be constructed with andThen(Function), and if a value retrieved from a ResultSet is nullable, usually this should pass unchanged through a chain of mappers as null. This eliminates the need for the mapping functions to handle nulls.
    This should be used for rare circumstances where the result from a function passed to andThen(Function) can be null. If mapping a nullable database column, consider using a NullableColumnMapper instead.
    
    Returns:
    
    a new ColumnMapper
