Interface	Description
Translator<T>	A translator knows how convert between POJO objects and the EntityNode tree structure that Objectify can persist.

Class Summary

Class	Description
AbstractTranslator<T>	Very simple helper for all kinds of translators.
ArrayTranslatorFactory	Translator which can load an array of things.
AsIsTranslatorFactory	This should be the last translator in the list - the one to try when nothing else wants the type.
ByteArrayTranslatorFactory	Translates a byte[] to Blob.
ClassTranslator<T>	Translator which knows what to do with a whole class.
CollectionTranslatorFactory	Translator which can load things into a collection field.
CollectionTranslatorFactory.CollectionListNodeTranslator
CreateContext	The context while creating translator factories.
EmbedClassTranslatorFactory<T>	Translator which can map whole embedded classes.
EntityClassTranslator<T>	Translator which can maps the root of an entity.
EnumTranslatorFactory	Knows how to convert Enums to the datastore String
KeyTranslatorFactory	Knows how to convert Key objects to datastore-native Key objects and vice-versa.
ListNodeTranslator<T>	Helper which expects a list node in the data structure and throws an exception one is not found.
LoadContext	The context of a load operation, which may extend across several entities (for example, a batch).
MapifyTranslatorFactory	This takes a collection and converts it to a map by letting you select out the key value using a class of your own devising.
MapifyTranslatorFactory.MapifyListNodeTranslator
MapNodeTranslator<T>	Helper which expects a map node in the data structure and throws an exception if a map is not found.
MapTranslatorFactory	Translator which manages an expando-style Map.
MapTranslatorFactory.MapMapNodeTranslator
NumberTranslatorFactory	Numbers are funky in the datastore.
PropertyValueNodeTranslator<T>	Helper which expects a property value in the data structure and throws an exception if one is not found.
RefTranslatorFactory	Knows how to convert Ref objects to datastore-native Key objects and vice-versa.
SaveContext	The context of a save operation; might involve multiple entities (eg, batch save).
SerializeTranslatorFactory	Loader which can load any serialized thing from a Blob.
SqlDateTranslatorFactory	The datastore can't store java.sql.Date, but it can do java.util.Date.
StringTranslatorFactory	Knows how to convert Strings.
TimeZoneTranslatorFactory	Converts java.util.TimeZone
TranslateTranslatorFactory	Translator factory which lets users define a custom translator for a field.
TranslatorRegistry	Manages all the translators used to map between POJO fields and the types that the Datastore can actually persist.
URLTranslatorFactory	The datastore can't store URL, so translate it to a String and back.
ValueTranslator<P,D>	Helper which helps take a mapnode's property value and converts it from datastore representation to pojo representation.
ValueTranslatorFactory<P,D>	Provides a little boilerplate for translators that work on simple atomic types.

Exception Summary

Exception	Description
SkipException	Thrown by any Translator that wants its value to be skipped.
