Data Components

Show the record and array types nested inside a selected record type, down to their primitive fields.

For a selected record type, this shows an edge to each of its components (fields), then an edge from that component to its own type — another record type or an array type — and recurses into that type's components in turn. An array component's node shows its bounds and element type, and if that element type is itself a record or array, the graph continues into its components too. A component whose type has no further components of its own, like a Float, is a leaf.

Rooted at Route below, the graph shows its components Path (a Navigation.Segment) and Stops (a Navigation.Waypoint_Array). Segment continues into its own components From, To, and Speeds; Waypoint_Array continues into its element type, Coordinate, which is shown again with its own X and Y components.

See the following code and corresponding graph

package Primitives is
   type Coordinate is record
      X, Y : Float;
   end record;

   type Speed_Array is array (1 .. 4) of Float;
end Primitives;

package Navigation is
   type Segment is record
      From   : Primitives.Coordinate;
      To     : Primitives.Coordinate;
      Speeds : Primitives.Speed_Array;
   end record;

   type Waypoint_Array is array (1 .. 10) of Primitives.Coordinate;
end Navigation;

package Routes is
   type Route is record
      Path  : Navigation.Segment;
      Stops : Navigation.Waypoint_Array;
   end record;
end Routes;

Data Components - 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.

Data Components - Cluster

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

Back to Data Components

Data Components - Compare

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

Back to Data Components

Data Components - Relationship

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

Data Components - Simplified

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