    `void` | `appendReferring(ReadableObjectId.Referring currentReferring)`

          protected com.fasterxml.jackson.annotation.ObjectIdResolver _resolver

  - ### Constructor Detail

    - #### ReadableObjectId

          public ReadableObjectId(com.fasterxml.jackson.annotation.ObjectIdGenerator.IdKey key)

  - ### Method Detail

    - #### setResolver

          public void setResolver(com.fasterxml.jackson.annotation.ObjectIdResolver resolver)

    - #### getKey

          public com.fasterxml.jackson.annotation.ObjectIdGenerator.IdKey getKey()

    - #### appendReferring

          public void appendReferring(ReadableObjectId.Referring currentReferring)

    - #### bindItem

          public void bindItem(java.lang.Object ob)
                        throws java.io.IOException

      Method called to assign actual POJO to which ObjectId refers to: will also handle referring properties, if any, by assigning POJO.
      Throws:
        `java.io.IOException`

    - #### resolve

          public java.lang.Object resolve()

    - #### hasReferringProperties

          public boolean hasReferringProperties()

    - #### referringProperties

          public java.util.Iterator<ReadableObjectId.Referring> referringProperties()

    - #### tryToResolveUnresolved

          public boolean tryToResolveUnresolved(DeserializationContext ctxt)

      Method called by `DeserializationContext` at the end of deserialization if this Object Id was not resolved during normal processing. Call is made to allow custom implementations to use alternative resolution strategies; currently the only way to make use of this functionality is by sub-classing `ReadableObjectId` and overriding this method.

      Default implementation simply returns `false` to indicate that resolution attempt did not succeed.

      Returns:
        True, if resolution succeeded (and no error needs to be reported); false to indicate resolution did not succeed.
      Since:
        2.6

    - #### getResolver

          public com.fasterxml.jackson.annotation.ObjectIdResolver getResolver()

      Allow access to the resolver in case anybody wants to use it directly, for examples from `DefaultDeserializationContext.tryToResolveUnresolvedObjectId(com.fasterxml.jackson.databind.deser.impl.ReadableObjectId)`.
      Returns:
        The registered resolver
      Since:
        2.7

    - #### toString

          public java.lang.String toString()

      Overrides:
        `toString` in class `java.lang.Object`
