Method Detail

• bindItem

  void bindItem(ObjectIdGenerator.IdKey id,
                Object pojo)

  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.

  Parameters:

  id - The Object Identifier

  pojo - The POJO associated to that Identifier

• resolveId

  Object resolveId(ObjectIdGenerator.IdKey id)

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

  Parameters:

  id - The Object Identifier

  Returns:

  The POJO, or null if unable to resolve.

• newForDeserialization

  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).

  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.

  Parameters:

  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.

• canUseFor

  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)).

  Returns:

  True if this instance can be used as-is; false if not
