Generic procedures

Generic procedures

[Tobias Ritzau]

I wonder if it is possible to have a generic procedure in a
package and do some instations in the same spec.

I have written a socket packet and in the package I have
generic put and get procedures. It would be nice if I could
instatiate the procedure with some standard types. Is this
possible?

It's not directly possible, because you can instantiate only after elaboration
of the generic's body. The following little package shows you how you can work
around the problem.


package p is
   
   generic
   procedure gp;

   procedure p; -- is new gp;

end p;

package body p is
   
   procedure gp is
   begin
      null;
   end gp;

   procedure pi is new gp;

   procedure p renames pi;

end p;

Generics typically are written to support code reuse.  With that, I
would suggest that you make the generic into a separate unit (outside of
your package)

This way, you can "With" the generic, and instantiate to your liking.
