Interface Adapter<POJO_TYPE,​JSON_TYPE>

  • Type Parameters:
    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.
    All Superinterfaces:
    MapperConverter
    All Known Subinterfaces:
    TypeAwareAdapter<A,​B>
    All Known Implementing Classes:
    ConverterAdapter, DateWithCopyConverter, LocaleConverter, ReversedAdapter, TimestampAdapter

    public interface Adapter<POJO_TYPE,​JSON_TYPE>
    extends MapperConverter
    An Adapter is similar to a 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.

     public static class DateHolderAdapter implements Adapter {

      • to

        POJO_TYPE to​(JSON_TYPE b)
        Transfer JSONTYPE_TYPE from JSON to POJO as POJO_TYPE.
      • from

        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.
