A.18.16 The Generic Package Containers.Indefinite_Ordered_Sets
{
AI95-00302-03}
The language-defined generic package Containers.Indefinite_Ordered_Sets
provides a set with the same operations as the package Containers.Ordered_Sets
(see
A.18.9), with the difference that the
generic formal type Element_Type is indefinite.
Static Semantics
{

{
AI05-0092-1}
The declaration of the generic library package Containers.Indefinite_Ordered_Sets
has the same contents and semantics as Containers.Ordered_Sets except:
The generic formal Element_Type is indefinite.
The actual Element parameter of access subprogram
Process of Update_Element_Preserving_Key may be constrained even if Element_Type
is unconstrained.
{
AI12-0035-1}
The operations Include, Insert, Replace, Replace_Element, and To_Set
that have a formal parameter of type Element_Type perform indefinite
insertion (see
A.18).
Ramification: This includes the procedure
Replace declared in the nested generic package Generic_Keys, as well
as the routines declared directly in the Containers.Indefinite_Ordered_Sets
package.

Inconsistencies With Ada 2012

Corrigendum: Defined some routines to “perform
indefinite insertion”. This could mean that some calls to those
routines would now raise Program_Error where they previously worked.
However, this is extremely unlikely; see Inconsistencies With Ada 2012
in
A.18.11 for details.
