封闭接口:

Deserializers

public static class Deserializers.Base
extends Object
implements Deserializers

Basic Deserializers implementation that implements all methods but provides no deserializers. Its main purpose is to serve as a base class so that sub-classes only need to override methods they need, as most of the time some of methods are not needed (especially enumeration and array deserializers are very rarely overridden).

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
