Modifier and Type | Method and Description |
---|---|
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. |
boolean |
hasSingleElement(java.util.Iterator<?> value)
Method called to determine if the given value (of type handled by
this serializer) contains exactly one element.
|
boolean |
isEmpty(SerializerProvider prov,
java.util.Iterator<?> value)
Method called to check whether given serializable value is
considered "empty" value (for purposes of suppressing serialization
of empty values).
|
void |
serialize(java.util.Iterator<?> value,
JsonGenerator gen,
SerializerProvider provider)
Method that can be called to ask implementation to serialize
values of type this serializer handles.

JsonSerializer
Default implementation will consider only null values to be empty.
NOTE: replaces JsonSerializer.isEmpty(Object)
, which was deprecated in 2.5

ContainerSerializer
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).
Note, too, that as of now (2.9) this method is only called by serializer
itself; and specifically is not used for non-array/collection types
like Map
or Map.Entry
instances.
