Annotation Type Serialize

@Retention(RUNTIME) @Target({TYPE,FIELD}) public @interface Serialize

When placed on an entity field, the field will be written as a single Blob property using java serialization. Can also be placed on a class to indicate that all fields of that type should be serialized.

  • The field can contain an arbitrary object graph.
  • All classes in the graph must follow Java serialization rules (ie, implement Serializable).
  • You will not be able to use the field or any child fields in queries.
  • Within serialized classes, transient (the java keyword) fields will not be stored. @Ignore fields *will* be stored!
  • @Serialize collections can be nested inside @Embed collections.
  • Java serialization is opaque to the datastore viewer and other languages (ie gae/python).

You are strongly advised to place serialVersionUID on all classes that you intend to store as @Serialize. Without this, any change to your classes will prevent stored objects from being deserialized on fetch.

  • Element Details

    • zip

      boolean zip
      If true, the data stream will be compressed on write using a DeflatorInputStream. This only affects writes; on read, Objectify will understand both compressed and uncompressed data.
      Default:
      false

    • compressionLevel

      int compressionLevel
      If zip is true, sets the compression level of the Deflater.
      Default:
      -1
