Deserializers

public class SimpleDeserializers
extends Object
implements Deserializers

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.

从接口复制的说明: 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).

指定者:

findArrayDeserializer 在接口中 Deserializers

参数:

type - Type of array instances to deserialize

config - Configuration in effect

provider - Provider that can be used to locate deserializer for component type (if one not provided, or needs to be overridden)

property - Property that contains array value (null for root values)

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)

返回:

Deserializer to use for the type; or null if this provider does not know how to construct it

抛出:

JsonMappingException
