 package com.fasterxml.jackson.annotation;
Definition of API used for constructing POJO from Object Identifiers (as annotated using JsonIdentityInfo).

public interface ObjectIdResolver {
Method called when a POJO is deserialized and has an Object Identifier. Method exists so that implementation can keep track of existing object in json stream that could be useful for further resolution.

id The Object Identifer
ob The POJO associated to that Identifier
    void bindItem(IdKey idObject pojo);

Method called when deserialization encounters the given Object Identifier and requires the POJO associated with it.

id The Object Identifier
The POJO, or null if unable to resolve.
    Object resolveId(IdKey id);

Factory method called to create a new instance to use for deserialization: needed since resolvers may have state (a pool of objects).

Note that actual type of 'context' is com.fasterxml.jackson.databind.DeserializationContext, but can not be declared here as type itself (as well as call to this object) comes from databind package.

context Deserialization context object used (of type com.fasterxml.jackson.databind.DeserializationContext ; may be needed by more complex resolvers to access contextual information such as configuration.
    ObjectIdResolver newForDeserialization(Object context);

Method called to check whether this resolver instance can be used for Object Ids of specific resolver type; determination is based by passing a configured "blueprint" (prototype) instance; from which the actual instances are created (using newForDeserialization(java.lang.Object)).

True if this instance can be used as-is; false if not
    boolean canUseFor(ObjectIdResolver resolverType);
