public class CollectionDeserializer
- extends StdDeserializer<Collection<Object>>
Basic serializer that can take Json "Array" structure and
construct a Collection
instance, with typed contents.
Note: for untyped content (one indicated by passing Object.class
as the type), UntypedObjectDeserializer
is used instead.
It can also construct List
s, but not with specific
POJO types, only other containers and primitives/wrappers.

CollectionDeserializer
public CollectionDeserializer(Class<?> collectionClass,
JsonDeserializer<Object> valueDeser)
deserialize
public Collection<Object> deserialize(JsonParser jp,
DeserializationContext ctxt)
throws IOException,
JsonProcessingException
- Description copied from class:
JsonDeserializer
- Method that can be called to ask implementation to deserialize
json content into the value type this serializer handles.
Returned instance is to be constructed by method itself.
Pre-condition for this method is that the parser points to the
first event that is part of value to deserializer (and which
is never Json 'null' literal, more on this below): for simple
types it may be the only value; and for structured types the
Object start marker.
Post-condition is that the parser will point to the last
event that is part of deserialized value (or in case deserialization
fails, event that was not recognized or usable, which may be
the same event as the one it pointed to upon call).
Note that this method is never called for JSON null literal,
and thus deserializers need (and should) not check for it.
- Specified by:
deserialize
in class JsonDeserializer<Collection<Object>>
- Parameters:
jp
- Parsed used for reading Json contentctxt
- Context that can be used to access information about
this deserialization activity.
- Returns:
- Deserializer value
- Throws:
IOException
JsonProcessingException
deserialize
public Collection<Object> deserialize(JsonParser jp,
DeserializationContext ctxt,
Collection<Object> result)
throws IOException,
JsonProcessingException
- Description copied from class:
JsonDeserializer
- Alternate deserialization method (compared to the most commonly
used,
JsonDeserializer.deserialize(JsonParser, DeserializationContext)
),
which takes in initialized value instance, which is to be
configured and/or populated by deserializer. Method is only
used for subset of all supported types; most commonly just
for Collections and Maps, but potentially also for beans/POJOs.
Default implementation just throws
UnsupportedOperationException
, to indicate that types
that do not explicitly add support do not expect to get the call.
- Overrides:
deserialize
in class JsonDeserializer<Collection<Object>>
- Throws:
IOException
JsonProcessingException
