public interface ObjectIdResolver
Definition of API used for resolving actual Java object from
Object Identifiers (as annotated using JsonIdentityInfo
).
Method Summary | |
---|---|
void |
bindItem(ObjectIdGenerator.IdKey id,
Object pojo)
Method called when a POJO is deserialized and has an Object Identifier. |
boolean |
canUseFor(ObjectIdResolver resolverType)
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) ). |
ObjectIdResolver |
newForDeserialization(Object context)
Factory method called to create a new instance to use for deserialization: needed since resolvers may have state (a pool of objects). |
Object |
resolveId(ObjectIdGenerator.IdKey id)
Method called when deserialization encounters the given Object Identifier and requires the POJO associated with it. |
Method Detail |
---|
void bindItem(ObjectIdGenerator.IdKey id, Object pojo)
id
- The Object Identiferpojo
- The POJO associated to that IdentifierObject resolveId(ObjectIdGenerator.IdKey id)
id
- The Object Identifier
ObjectIdResolver newForDeserialization(Object context)
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.boolean canUseFor(ObjectIdResolver resolverType)
newForDeserialization(java.lang.Object)
).
