In JPA does an entity have access to the Embedded of its Embedded object?

Question

Does an entity have access to an Embedded of its Embedded object? Eg:

@Embeddable
public class Address {
    @Embedded
    protected AddressResearchChangeActivity activity;
}

public class ClaimantAddress {
    @Embedded
    private Address address;
}

So can ClaimantAddress access the AddressResearchChangeActivity ?

And when we save ClaimantAddress will the data of AddressResearchChangeActivity also be saved?

Answer 1

Embedded objects are just a way to group several fields inside an entity. When you save an entity, everything is saved in the entity, including all the embedded objects (and their sub-embedded objects).
