What do you want from Room when you create a DAO method and annotate it with @Delete?
Example:
@Dao
public interface MyDao {
@Delete
public void deleteUsers(User… users);
}
A . Room generates an implementation that inserts all parameters into the database in a single transaction.
B . Room modifies a set of entities, given as parameters, in the database. It uses a query
that matches against the primary key of each entity.
C . Room removes a set of entities, given as parameters, from the database. It uses the primary keys to find the entities to delete.
