|
|
---Purpose : A SelectEntityNumber gets in an InterfaceModel (through a

|
-- Graph), the Entity which has a specified Number (its rank of
|
|
-- adding into the Model) : there can be zero (if none) or one.
|
|
-- The Number is not directly defined as an Integer, but as a

|
|
---Purpose : Creates a SelectEntityNumber, initially with no specified Number

|
---Purpose : Sets Entity Number to be taken (initially, none is set : 0)

|
---Purpose : Returns the list of selected entities : the Entity having the
