Class MapifyTranslatorFactory

java.lang.Object

com.googlecode.objectify.impl.translate.MapifyTranslatorFactory

All Implemented Interfaces:

TranslatorFactory<Map<Object,Object>>

public class MapifyTranslatorFactory
extends Object
implements TranslatorFactory<Map<Object,Object>>

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. All the rules for collections normally apply (ie, you can't have collections inside of collections) but otherwise this works just like a map. The values will be written to the collection, not the keys.

Method Detail

create

public Translator<Map<Object,Object>> create(Path path,
                                    Property property,
                                    Type type,
                                    CreateContext ctx)

Specified by:

create in interface TranslatorFactory<Map<Object,Object>>

Parameters:

path - current path to this part of the tree, important for logging and exceptions

property - is the property we are inspecting to create a translator for

type - is the generic type of the field (or field component). For example, examining a field of type List will have a Type of List; the TranslatorFactory which recognizes List may then ask for a translator of its component type String.

Returns:

null if this factory does not know how to deal with that situation.
