generic package with configuration paramenter

generic package with configuration paramenter

[Tilman Glotzner]

Hello,

I am writting a generic package and I would like to add to add a
configuring
parameter when instanciating the package that is defined within the
generic package.

generic
type T_ITEM is private;
MODE: T_MODE; -- type T_MODE is (FIFO,FILO);
package LIST is
...
end LIST;

Where can I define T_MODE ? Do I need to define T_MODE in a package
wrapped around the generic package:

package L is
type T_MODE is (FIFO,FILO); 
generic
type T_ITEM is private;
MODE: T_MODE;
pacakge LIST is
..
end LIST;

Or can I define it with the generic package ?


Thanks,

Tilman

Why not try:

generic
    type T_ITEM is private;
    Mode_Fifi : Boolean;
package LIST is
   .......
end LIST

then you wont need to declare type Mode_T at all :-)

This should be adequate.

Another way is to declare the type in a "root package," and then make the
generic package a (public) child:

package P is
   type Mode_Type is (FIFO, LIFO);
end P;

generic
   Mode : in Mode_Type;
package P.GQ is
   type List_Type is private;
...
end P.GQ;


This way you can share this type among instantiations and other children of
P.

Put it in a different package, made visible by 'with':
package L is 
   type T_MODE is (FIFO, FILO);
end L;

with L;
generic 
   type T_ITEM is private;
   MODE : T_MODE;
package LIST is
...
end LIST

package L is
   type T_MODE is (FIFO, LIFO);
end L;

with L;
generic
   type T_ITEM is private;
   MODE : L.T_MODE;
package LIST is
...
end LIST;
