POJO_TYPE - The Java type in the POJO (Plain Old Java Object)JSON_TYPE - The Java Type which will be used to transform to JSON.public interface Adapter<POJO_TYPE,JSON_TYPE> extends MapperConverter
Converter.
 The main difference is that a Converter always converts from/to a String.
 An adapter might e.g. convert to a Date or any other Object which will
 then be json-ified.
 A small example which has a special Java type to internally represent dates.
 Let's call it DateHolder.
 Our Mapper should treat it as a java.util.Date.
 For doing so we create a DateHolderAdapter like the following example shows:
 
public static class DateHolderAdapter implements Adapter{ 
| Modifier and Type | Method and Description | 
|---|---|
| JSON_TYPE | from(POJO_TYPE a)Take the POJO_TYPE object A from a POJO an convert it to JSON_TYPE which will be inserted into the JSON output. | 
| POJO_TYPE | to(JSON_TYPE b)Transfer JSONTYPE_TYPE from JSON to POJO as POJO_TYPE. |
