Type Tree

Show the Ada types directly or indirectly derived from a selected type.

For a selected Ada tagged type, this shows an edge to each type that directly derives from it, then recurses into each of those types’ own descendants, building a multi-level tree.

Rooted at Calibrated_Sensor below, the graph shows edges to its two direct descendants, Temperature_Sensor and Pressure_Sensor. Temperature_Sensor continues to Thermocouple, and Pressure_Sensor continues to Barometer. The inverse graph, Type Derived From, shows the reverse relationship — everything the selected type derives from, directly or indirectly.

See the following code and corresponding graph

with Analog;

package Calibrated is

   type Calibrated_Sensor is new Analog.Analog_Sensor with record
      Offset : Float := 0.0;
      Scale  : Float := 1.0;
   end record;

end Calibrated;

with Calibrated;

package Temperature is

   type Temperature_Sensor is
      new Calibrated.Calibrated_Sensor with record
      Unit : Character := 'C';
   end record;

   type Thermocouple is new Temperature_Sensor with record
      Junction_Type : Character := 'K';
   end record;

end Temperature;

with Calibrated;

package Pressure is

   type Pressure_Sensor is
      new Calibrated.Calibrated_Sensor with record
      Unit : Character := 'P';
   end record;

   type Barometer is new Pressure_Sensor with record
      Altitude_Compensation : Float := 0.0;
   end record;

end Pressure;

Type Tree - 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.

Type Tree - Cluster

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

Back to Type Tree

Type Tree - Compare

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

Back to Type Tree

Type Tree - Relationship

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

Type Tree - Simplified

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