public class SimpleDeserializers extends Deserializers.Base implements Serializable
Simple implementationDeserializers
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 (likeMap
s andCollection
s or array types).Unlike
SimpleSerializers
, this class does not currently support generic mappings; all mappings must be to exact declared deserialization type.- See Also:

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.

hasDeserializerFor
public boolean hasDeserializerFor(DeserializationConfig config, Class<?> valueType)
Description copied from class:Deserializers.Base
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 this implementation since adding new methods for interfaces before Java 8 is not a good idea: will be added in Jackson 3.0 for `Deserializers`.
