All Implemented Interfaces:
  Serializable

    public class EntityConverter

extends Converter

A subclass of Converter that allows specifying keys to be deleted.

When a Converter is used with an entity class, secondary keys cannot be automatically deleted based on field deletion, because field Deleter objects are not used in conjunction with a Converter mutation. The EntityConverter can be used instead of a plain Converter to specify the key names to be deleted.

It is not currently possible to rename or insert secondary keys when using a Converter mutation with an entity class.
