What do you want from Room when you create a DAO method and annotate it with @Delete?
Example:
@Dao
interface MyDao {
@Delete
fun deleteUsers(vararg users: User)
}
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.
Example:
@Dao
interface MyDao {
@Delete
fun deleteUsers(vararg users: User)
}
