    Method
    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.
    <T> void
    registerConversionToDatabase(@NotNull Class<T> source, @NotNull Function<T,?> conversion)
    Registers conversion from given source model type to database type.
    <T extends Enum<T>, K>
    void
    registerEnumConversion(@NotNull Class<T> enumType, @NotNull Function<T,K> keyFunction)
    Registers simple enum conversion that uses keyFunction to produce saved value and uses same function on enum constants to convert values back.
    default <T extends Enum<T>>
    void
    registerNativeEnumConversion(@NotNull Class<T> enumType, @NotNull String typeName)
    Returns given enum-type to be saved as database native enum of given type name.
    <T extends Enum<T>, K>
    void
    registerNativeEnumConversion(@NotNull Class<T> enumType, @NotNull String typeName, @NotNull Function<T,K> keyFunction)
    Returns given enum-type to be saved as database native enum of given type name.
