How to store null fields with Morphia

Morphia does not store null/empty fields by default. Is there a way to enable this?

In the interests of answering the question asked, you can:

• store nulls by configuring MapperOptions.setStoreNulls(boolean)
• store empty values by configuring MapperOptions.setStoreEmpties(boolean).

You can get a MapperOptions reference from the mapper instance by Mapper.getOptions().

Deprecation Update

However, the Mapper class is internal only and is deprecated:

this class will be internalized in 2.0

Same deprecation applies for before mentioned setter methods in class MapperOptions, instead the JavaDocs recommend:

use the Builder instead
