Alternate constructor that is (alas!) needed to work
around kinks of generic type handling

protected abstract ContainerSerializer<?> |
_withValueTypeSerializer(TypeSerializer vts)
Method that needs to be implemented to allow construction of a new
serializer object with given
TypeSerializer , used when
addition type information is to be embedded. |
abstract JsonSerializer<?> |
getContentSerializer()
Accessor for serializer used for serializing contents
(List and array elements, Map values etc) of the
container for which this serializer is used, if it is
known statically.
|
abstract JavaType |
getContentType()
Accessor for finding declared (static) element type for
type this serializer is used for.
|
protected boolean |
hasContentTypeAnnotation(SerializerProvider provider,
BeanProperty property)
Helper method used to encapsulate logic for determining whether there is
a property annotation that overrides element type; if so, we can
and need to statically find the serializer.
|
abstract boolean |
hasSingleElement(T value)
Method called to determine if the given value (of type handled by
this serializer) contains exactly one element.
|
boolean |
isEmpty(T value)
Deprecated.
|
ContainerSerializer<?> |
withValueTypeSerializer(TypeSerializer vts)
Factory(-like) method that can be used to construct a new container
serializer that uses specified
TypeSerializer for decorating
contained values with additional type information. |

Note: although it might seem sensible to instead define something like "getElementCount()" method, this would not work well for containers that do not keep track of size (like linked lists may not).
