public class SimpleDeserializers extends Object implements Deserializers, 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 Map
s and Collection
s
or array types).
Unlike SimpleSerializers
, this class does not currently support generic mappings;
all mappings must be to exact declared deserialization type.

Deserializers
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).

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)
).
