Methods

Modifier and Type	Method and Description
Collection<String>	deserialize(JsonParser jp, DeserializationContext ctxt) Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles.
Collection<String>	deserialize(JsonParser jp, DeserializationContext ctxt, Collection<String> result) Alternate deserialization method (compared to the most commonly used, JsonDeserializer.deserialize(JsonParser, DeserializationContext)), which takes in initialized value instance, to be configured and/or populated by deserializer.
Object	deserializeWithType(JsonParser jp, DeserializationContext ctxt, TypeDeserializer typeDeserializer) Base implementation that does not assume specific type inclusion mechanism.
JsonDeserializer<Object>	getContentDeserializer() Accesor for deserializer use for deserializing content values.
JavaType	getContentType() Accessor for declared type of contained value elements; either exact type, or one of its supertypes.
void	resolve(DeserializationConfig config, DeserializerProvider provider) Method called to finalize setup of this deserializer, after deserializer itself has been registered.

Method Detail

resolve

public void resolve(DeserializationConfig config,
           DeserializerProvider provider)
             throws JsonMappingException

Method called to finalize setup of this deserializer, after deserializer itself has been registered. This is needed to handle recursive and transitive dependencies.

Specified by:

resolve in interface ResolvableDeserializer

provider - Provider that has constructed deserializer this method is called on.

Throws:

JsonMappingException

getContentType

public JavaType getContentType()

Description copied from class: ContainerDeserializerBase

Accessor for declared type of contained value elements; either exact type, or one of its supertypes.

Specified by:

getContentType in class ContainerDeserializerBase<Collection<String>>

getContentDeserializer

public JsonDeserializer<Object> getContentDeserializer()

Description copied from class: ContainerDeserializerBase

Accesor for deserializer use for deserializing content values.

Specified by:

getContentDeserializer in class ContainerDeserializerBase<Collection<String>>

deserialize

public Collection<String> 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<String>>

Parameters:

jp - Parsed used for reading JSON content

ctxt - Context that can be used to access information about this deserialization activity.

Returns:

Deserializer value

Throws:

IOException

JsonProcessingException

deserialize

public Collection<String> deserialize(JsonParser jp,
                             DeserializationContext ctxt,
                             Collection<String> 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, to be configured and/or populated by deserializer. Method is not necessarily used for all supported types; most commonly it is used for Collections and Maps.

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<String>>

Throws:

IOException

JsonProcessingException

deserializeWithType

public Object deserializeWithType(JsonParser jp,
                         DeserializationContext ctxt,
                         TypeDeserializer typeDeserializer)
                           throws IOException,
                                  JsonProcessingException

Description copied from class: StdDeserializer

Base implementation that does not assume specific type inclusion mechanism. Sub-classes are expected to override this method if they are to handle type information.

Overrides:

deserializeWithType in class StdDeserializer<Collection<String>>

typeDeserializer - Deserializer to use for handling type information

Throws:

IOException

JsonProcessingException
