Annotation Type LongConversion

@Retention(value=RUNTIME)
 @Target(value={ANNOTATION_TYPE,FIELD,PARAMETER})
public @interface LongConversion

Meta-annotation used to associate a concrete LongConverter implementation with another annotation. Custom marker annotations (for example @Hexadecimal or @Base64) can declare which converter should be applied when serialising or deserialising long fields or parameters. The referenced converter annotation should either have a static final instance named `INSTANCE` or should be a LongConverter

Example usage:

 @LongConversion(HexadecimalLongConverter.class)
 @Retention(RetentionPolicy.RUNTIME)
 @Target({ElementType.FIELD, ElementType.METHOD, ElementType.PARAMETER})
 public @interface MyHexFormat {
     LongConverter INSTANCE = new MyHexFormatConverter("0123456789ABCDEF");
 }
