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.

Overrides default tools.jackson.databind.deser.Deserializers.findArrayDeserializer.

Doc from tools.jackson.databind.deser.Deserializers.findArrayDeserializer.

Method called to locate deserializer 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).

Method called to locate deserializer for specified java.util.Map 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 of map serializer constructed here.

Implements tools.jackson.databind.deser.Deserializers.hasDeserializerFor.

Doc from tools.jackson.databind.deser.Deserializers.hasDeserializerFor.

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.
