public class SimpleDeserializers extends Deserializers.Base implements Serializable
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.

DeserializersMap 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).
Similarly, a KeyDeserializer may be passed, but this is only done if there is
a specific configuration override (annotations) to indicate instance to use.
Otherwise null is passed, and key deserializer needs to be obtained later during
resolution (using ResolvableDeserializer.resolve(com.fasterxml.jackson.databind.DeserializationContext)).

DeserializersNote: 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.
