All Implemented Interfaces:
Deserializers, Serializable
public class SimpleDeserializers extends Deserializers.Base implements Serializable
Simple implementation Deserializers which allows registration of deserializers based on raw (type erased class). It can work well for basic bean and scalar type deserializers, but is not a good fit for handling generic types (like Maps and Collections or array types).

Unlike SimpleSerializers, this class does not currently support generic mappings; all mappings must be to exact declared deserialization type.

    • findArrayDeserializer

      public JsonDeserializer<?> findArrayDeserializer(ArrayType type, DeserializationConfig config, BeanDescription beanDesc, TypeDeserializer elementTypeDeserializer, JsonDeserializer<?> elementDeserializer) throws JsonMappingException
      Description copied from interface: Deserializers
      Method called to locate serializer for specified array type.

      Deserializer for element type may be passed, if configured explicitly at higher level (by annotations, typically), but usually are not. Type deserializer for element is passed if one is needed based on contextual information (annotations on declared element class; or on field or method type is associated with).

      Specified by:
      findArrayDeserializer in interface Deserializers
      Overrides:
      findArrayDeserializer in class Deserializers.Base
      Parameters:
      type - Type of array instances to deserialize
      config - Configuration in effect
      beanDesc - Definition of the enumeration type that contains class annotations and other information typically needed for building deserializers
      elementTypeDeserializer - If element type needs polymorphic type handling, this is the type information deserializer to use; should usually be used as is when constructing array deserializer.
      elementDeserializer - Deserializer to use for elements, if explicitly defined (by using annotations, for exmple). May be null, in which case it should be resolved here (or using ResolvableDeserializer callback)
      Returns:
      Deserializer to use for the type; or null if this provider does not know how to construct it
      Throws:
      JsonMappingException

    • hasDeserializerFor

      public boolean hasDeserializerFor(DeserializationConfig config, Class<?> valueType)
      Description copied from interface: Deserializers
      Method that may be called to check whether this deserializer provider would provide deserializer for values of given type, without attempting to construct (and possibly fail in some cases) actual deserializer. Mostly needed to support validation of polymorphic type ids.

      Note: implementations should take care NOT to claim supporting types that they do not recognize as this could to incorrect assumption of safe support by caller.

      Method added in Jackson 2.13 now that Java 8 default implementations are available for use with interface definitions.
