Object creation and validation

Custom Destination Object Creation

You can provide a function call to create your destination objects instead of using the default object creation (which expects an empty constructor). To do so, use the ConstructUsing method when configuring. This method expects a function that will provide the destination instance. You can call your own constructor, a factory method, or anything else that provides an object of the expected type.

//Example using a non-default constructor
TypeAdapterConfig<TSource, TDestination>.NewConfig()
            .ConstructUsing(src => new TDestination(src.Id, src.Name));

//Example using an object initializer
TypeAdapterConfig<TSource, TDestination>.NewConfig()
            .ConstructUsing(src => new TDestination{Unmapped = "unmapped"});

After mapping action

You can perform actions after each mapping by using AfterMapping method. For instance, you might would like to validate object after each mapping.

TypeAdapterConfig<Foo, Bar>.ForType().AfterMapping((src, dest) => dest.Validate());

Or you can set for all mappings to types which implemented a specific interface by using ForDestinationType method.

TypeAdapterConfig.GlobalSettings.ForDestinationType<IValidatable>()
                                .AfterMapping(dest => dest.Validate());
