To avoid code duplication, could you refactor the old deprecated class to keep only the public method and make it call the one in the new class?

Hello, yeah i will consider that.

[pavly-gerges]

Done, @riccardobl you could review it now.

EDIT:

• This PR should close this issue #1825.

I think the new class should not call the deprecated class, it should be vice-versa. I think this is also what @riccardobl meant.

Oh, i must have misunderstood this, okay i am going to refactor this.

EDIT: There is a small question though, should i move the private methods from the deprecated class to the new one ? I think they should be moved, so in case if we want to modify them later....
