public class StringCollectionSerializer extends StaticListSerializerBase<Collection<String>> implements ContextualSerializer
Collection
s that contain Strings.
The only complexity is due to possibility that serializer for String
may be overridde; because of this, logic is needed to ensure that the default
serializer is in use to use fastest mode, or if not, to defer to custom

JsonSerializer
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
need to be properly handled with respect to serializing of contents.
