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.
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 can not provide it and null is passed instead (in which case impls usually pass 'this' deserializer as is)
