Generic type

Generic type

[Matthias Teege]

Moin,

I've wrote an generic packages to store things in an
table. The generic looks like this: 

generic

   Rows : in Positive;       -- Length of table
   type Info (<>) is private;

package Table is

   type Tabelle is limited private; 
   subtype Id is Positive range 1 .. Rows;
..

I made a new instance with this statement: 

package Cline is
   new Table (Kapazitaet => 10, Nutz_Info =>
   String);

wich works great. But how can I use my own types?

type Argument;
package Cline is
   new Table (Kapazitaet => 10, Nutz_Info => Argument);

wont work. ;-)

Many thanks
Matthias

That's because Argument hasn't been fully defined. You'll have to move
the definition of "Cline" to after the full definition of "Argument" if
you want to use Argument as an actual.

Well...it could *also* be because you got the names of the formals wrong
in the declaration, but I'll assume that's a typo. :-)
