External mapper injection

[sonytricoire]

I need to inject an existing mapper into another mapper to avoid duplication mapping rules.

For example, if want to inject an existing mapper to manage the ConfigProfile class mapping, I expect something like

mapper1 = new Mapper()
                .biMapping(ConfigProfile.class, ConfigProfileDTO.class);
...
mapper = new Mapper()
                .biMapping(Device.class, DeviceDTO.class)
                .injectMapper(mapper1, ConfigProfile.class);

What I would do to avoid duplication is to have only one Mapper instance for all the mappings, as Mapper is thread-safe and there shouldn't be conflicting cases.

In your .injectMapper(mapper1, ConfigProfile.class), what is ConfigProfile.class for ?

If that means "I want the ConfigProfile class to be mapped only by mapper1, then what about that :

Mapper mapper = new Mapper()
    .custom(new CustomMapper<ConfigProfile, ConfigProfileDTO >() {
        @Override
        public ConfigProfileDTO customMapping(ConfigProfile source) {
            return mapper1.map(source); // or anything else
        }
    };
});

I think it's better because it allows for other mapping libraries to be easily integrated in simple-mapper.

Would it be ok for you ?

Yep seems right !
