class ConnectedInteractive from AIS inherits InteractiveObject from AIS
---Purpose: Defines an Interactive Object through a connection to
-- another Interactive Object, which serves as a
-- reference, and which is located elsewhere in the viewer.
-- This allows you to use the Connected Interactive
-- Object without having to recalculate presentation,
-- selection or graphic structure. These are deduced
-- from your reference object.
-- The relation between the connected interactive object
-- and its source is generally one of geometric transformation.
-- Warning
-- An Interactive entity which is view (or projector)
-- dependent requires recalculation of views in hidden
-- parts mode depending on the position of the
-- projector in each view. You should derive the entity's
-- inheritance from ConnectedInteractive and redefine
-- its compute method to enable this type of calculation.

-- Disconnects the previous view and sets highlight
-- mode to 0. This highlights the wireframe presentation
-- aTypeOfPresentation3d.
-- Top_AllView deactivates hidden line removal.

---Purpose: Returns KOI_Object

---Purpose: Returns 1

---Purpose: Establishes the connection between the Connected
-- Interactive Object, anotherIobj, and its reference
-- entity. If a previous connection with an Interactive
-- Object already exists, it is removed by Disconnect.
-- The second syntax also initiates the location of the
-- Connected Interactive Object.

---Purpose:
-- Returns true if there is a connection established
-- between the presentation and its source reference.

---Purpose:
-- Returns the connection with the reference Interactive Object.

---Purpose: Clears the connection with a source reference. The

-- The latter are managed by aPresentationManager.
-- The display mode aMode is 0 by default.
-- this method is redefined virtual;
-- when the instance is connected to another
-- InteractiveObject,this method doesn't
-- compute anything, but just uses the
-- presentation of this last object, with
-- a transformation if there's one stored.

---Purpose: Computes the presentation according to a point of view
-- given by <aProjector>.
-- To be Used when the associated degenerated Presentations
-- have been transformed by <aTrsf> which is not a Pure
-- Translation. The HLR Prs can't be deducted automatically
-- WARNING :<aTrsf> must be applied

-- of the application.

---Level: Public
---Purpose: Recovers and calculates any sensitive primitive,
-- aSelection, available in Shape mode, specified by
-- aMode. As a rule, these are sensitive faces.
-- This method is defined as virtual. This enables you to
-- implement it in the creation of a new class of
-- Interactive Object. You need to do this and in so
-- doing, redefine this method, if you create a class
-- which enriches the list of signatures and types.

---Purpose: For this class, the location effect is treated in the
-- compute & computeSelection methods. So the
-- UpdateLocation Methods are redefined to do nothing else
-- UpdateLocation(me:mutable;P : mutable Presentation from Prs3d) is redefined virtual;
