Default implementation will throw UnsupportedOperationException
to indicate that proper type handling needs to be implemented.
For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like:
// note: method to call depends on whether this type is serialized as JSON scalar, object or Array! typeSer.writeTypePrefixForScalar(value, gen); serialize(value, gen, provider); typeSer.writeTypeSuffixForScalar(value, gen);and implementations for type serialized as JSON Arrays or Objects would differ slightly, as
START-ARRAY
/END-ARRAY
and
START-OBJECT
/END-OBJECT
pairs

JsonSerializer
Default implementation will return null, which essentially means
same as returning Object.class
would; that is, that
nothing is known about handled type.

null is passed instead (in which case impls usually pass 'this' serializer as is)JsonMappingException
