Class NumberTranslatorFactory

java.lang.Object

com.googlecode.objectify.impl.translate.NumberTranslatorFactory

All Implemented Interfaces:

TranslatorFactory<Number>

public class NumberTranslatorFactory
extends Object
implements TranslatorFactory<Number>

Numbers are funky in the datastore. You can save numbers of any size, but they always retrieve as Long. For the hell of it, we also handle String in the datastore by trying to parse it.

Not a ValueTranslatorFactory because Numbers are not assignable to primitives. Java lame.

Method Detail

create

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

Specified by:

create in interface TranslatorFactory<Number>

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.
