Method Summary

Modifier and Type	Method and Description
<S,T> void	registerConversionFromDatabase(@NotNull Class<S> source, @NotNull Class<T> target, @NotNull Function<S,T> conversion) Registers conversion from given source database type to given target model type.
default <D,J> void	registerConversions(@NotNull Class<D> databaseType, @NotNull Class<J> javaType, @NotNull Function<D,J> fromDatabase, @NotNull Function<J,D> toDatabase) Registers conversions from database type to model type and back.
