afMorphia::Converter
Implement to convert custom Fantom types to / from a MongoDB representation.
For more control over how a specific Fantom type is mapped to / from Mongo documents, create an implementation of Converter
for that type. Then, in the AppModule
, contribute an instance of the Converter
to the Converters
service:
@Contribute { serviceType=Converters# } static Void contributeConverters(Configuration config) { config[MyType#] = MyTypeConverter() }
The contribution key must be the type that the converter, converts.
