Instantiations

Show every instantiation of a selected Ada generic package, function, procedure, or task.

For a selected generic unit, this shows an edge to each package, function, procedure, or task instantiated from it. An instantiation doesn’t itself introduce a new generic to instantiate from, so this is always a single level and doesn’t recurse further.

Rooted at the generic package Generic_Stack below, the graph shows edges to its three instantiations: Integer_Stack, Float_Stack, and Character_Stack.

See the following code and corresponding graph

generic
   type Element is private;
   Capacity : Positive;
package Generic_Stack is
   type Stack is limited private;

   procedure Push     (S : in out Stack; Item :     Element);
   procedure Pop      (S : in out Stack; Item : out Element);
   function  Is_Empty (S : Stack) return Boolean;
   function  Is_Full  (S : Stack) return Boolean;

private
   type Element_Array is array (1 .. Capacity) of Element;
   type Stack is record
      Data : Element_Array;
      Top  : Natural := 0;
   end record;
end Generic_Stack;

with Generic_Stack;

package Instances is

   package Integer_Stack is new Generic_Stack
     (Element => Integer, Capacity => 64);

   package Float_Stack is new Generic_Stack
     (Element => Float, Capacity => 32);

   package Character_Stack is new Generic_Stack
     (Element => Character, Capacity => 128);

end Instances;

Instantiations - Classic

The Classic variant is similar to the Simplified variant, showing all relationships in a simple tree, but it uses a custom layout algorithm instead of Graphviz.

Instantiations - Cluster

The Cluster variant groups entities by their containing class/file/architecture.

Instantiations - Compare

The Compare variant shows how the graph has changed relative to the project's comparison database.

Instantiations - Relationship

The Relationship variant filters the graph to only paths connecting the two entities.

Instantiations - Simplified

The Simplified variant shows all relationships in a simple tree (no clusters)
