A.18.13 The Generic Package Containers.Indefinite_Hashed_Maps
The language-defined generic package Containers.Indefinite_Hashed_Maps provides a map with the same operations as the package Containers.Hashed_Maps (see A.18.5), with the difference that the generic formal types Key_Type and Element_Type are indefinite.
Static Semantics
The declaration of the generic library package Containers.Indefinite_Hashed_Maps has the same contents and semantics as Containers.Hashed_Maps except:
- The generic formal Key_Type is indefinite.
- The generic formal Element_Type is indefinite.
- The procedure with the profile:
procedure Insert (Container : in out Map;
Key : in Key_Type;
Position : out Cursor;
Inserted : out Boolean);
Key : in Key_Type;
Position : out Cursor;
Inserted : out Boolean);
is omitted.
- The actual Element parameter of access subprogram Process of Update_Element may be constrained even if Element_Type is unconstrained.
- The operations Include, Insert, Replace, and Replace_Element that have a formal parameter of type Element_Type perform indefinite insertion (see A.18).
- The description of Tampering_With_Elements_Prohibited is replaced by:
Returns True if tampering with elements is prohibited for Container, and False otherwise.
- Tampering_With_Cursors_Prohibited is replaced by Tampering_With_Elements_Prohibited in the postcondition for the operations Reference and Constant_Reference.
- The operations Replace and Replace_Element are omitted from the nested package Stable.
