public interface ContextualDeserializer
JsonDeserializers can implement to get a callback
that can be used to create contextual (context-dependent) instances of
deserializer to use for handling properties of supported type.
This can be useful
for deserializers that can be configured by annotations, or should otherwise
have differing behavior depending on what kind of property is being deserialized.
Note that in cases where deserializer needs both contextualization and
resolution -- that is, implements both this interface and
-- resolution via
ResolvableDeserializer occurs first, and contextual
resolution (via this interface) later on.
|Modifier and Type
|Method and Description
Method called to see if a different (or differently configured) deserializer is needed to deserialize values of specified property.
JsonDeserializer<?> createContextual(DeserializationContext ctxt, BeanProperty property) throws JsonMappingException
ctxt - Deserialization context to access configuration, additional
deserializers that may be needed by this deserializer
property - Method, field or constructor parameter that represents the property
(and is used to assign deserialized value).
Should be available; but there may be cases where caller cannot provide it and
null is passed instead (in which case impls usually pass 'this' deserializer as is)
