What is the meaning of the CascadeType.ALL for a @ManyToOne JPA association

I think I misunderstood the meaning of cascading in the context of a @ManyToOne relationship.

The case:

public class User {

   @OneToMany(fetch = FetchType.EAGER)
   protected Set<Address> userAddresses;

}

public class Address {

   @ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
   protected User addressOwner;

}

What is the meaning of the cascade = CascadeType.ALL? For example, if I delete a certain address from the database, how does the fact that I added the cascade = CascadeType.ALL affect my data (the User, I guess)?
