Listing 9.9. Using a
JsonBuilder
to produce nested links
One special quirk is notable here. The method calls
toString
on the individual
Link
in-
stances. As the JavaDocs for
Link
make clear, the
toString
and
valueOf(String)
methods in
Link
are used to convert to and from strings.
The
MessageBodyReader
interface is quite similar. In that case there are only two
methods:
isReadable
and
readFrom
. The implementation of
isReadable
is the
same as the
isWriteable
method:
public boolean isReadable(Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
type == Person && mediaType == MediaType.APPLICATION_JSON_TYPE
}
The
readFrom
method uses a
JsonSlurper
to convert string input into a
Person
, as
shown in the next listing.
