Question

I have the following code on my Hibernate class:

public List<Something> getSomethingList(Integer[] ls){
    String sql = "FROM SOMETHING WHERE IDSOMETHING IN (:ls)";

    return this.getSession().createQuery(sql).setParameterList("ls", ls).list();
}

I Have an warning on the return line. The warning is the following:

Type safety: The expression of type List needs unchecked conversion to conform to List<Something>

I know this is not a big issue but how can I solve this warning?

Thanks

Answer 1

First Option:
THIS:

 List<Permission> permissions = Collections.checkedList(Permission.class, this.getSession().createQuery(sql).setParameterList("ls", ls).list());

Should be like this:

List<Permission> permissions = Collections.checkedList(this.getSession().createQuery(sql).setParameterList("ls", ls).list(),Permission.class);

Second Option:

Use:

  @SuppressWarnings("unchecked")

Personally, I like the second option.
