Re: question on objects/package relationships

[Marin David Condic <mcondic.nospam@acm.org>]

It depends a little on what you are trying to accomplish and exactly how
you define your A and B objects. It would be legal to do something like
this:

package X is
    A : Integer ;
end X ;

package Y is
    B : Integer ;
    function What_Is_A return Integer ;
end Y ;

with X ;
package body Y is
    function What_Is_A return Integer is
    begin
        return X.A ;
    end What_Is_A ;
end Y ;

Note that if A gets defined in the private part of X, you could not do
this. As long as you have visibility it should be just fine. The
compiler will definitely tell you if you don't have visibility of A.

Hope this answers your question.
