KeyDeserializers can implement to get a callback
that can be used to create contextual instances of key deserializer to use for
handling Map keys of supported type. This can be useful
for key deserializers that can be configured by annotations, or should otherwise
have differing behavior depending on what kind of Map property keys are being deserialized.
| Modifier and Type | Method and Description |
|---|---|
| public KeyDeserializer | Returns: Key deserializer to use for deserializing keys specified Map property, may be this instance or a new instance.Deserialization context to access configuration, additional
deserializers that may be needed by this deserializer ctxt, BeanProperty Method, field or constructor parameter that declared Map for which
contextual instance will be used. Will not be available when deserializing root-level
Map value; otherwise should not be null. property)Method called to see if a different (or differently configured) key deserializer is needed to deserialize keys of specified Map property. |
| createContextual | back to summary |
|---|---|
| public KeyDeserializer createContextual(DeserializationContext ctxt, BeanProperty property) throws JsonMappingException Method called to see if a different (or differently configured) key deserializer is needed to deserialize keys of specified Map property. Note that instance that this method is called on is typically shared one and as a result method should NOT modify this instance but rather construct and return a new instance. This instance should only be returned as-is, in case it is already suitable for use.
