The language-defined generic package Containers.Bounded_Ordered_Maps
provides a private type Map and a set of operations. It provides the
same operations as the package Containers.Ordered_Maps (see A.18.6),
with the difference that the maximum storage is bounded.

{*AI05-0001-1*}
The declaration of the generic library package
Containers.Bounded_Ordered_Maps has the same contents and semantics as
Containers.Ordered_Maps except:

The
type Map is declared with a discriminant that specifies the capacity
(maximum number of elements) as follows:

The type Map needs finalization
if and only if type Key_Type or type Element_Type needs finalization.

The allocation of a new node
includes a check that the capacity is not exceeded, and Capacity_Error
is raised if this check fails.

In procedure Assign, if Source
length is greater than Target capacity, then Capacity_Error is propagated.

The
function Copy is replaced with:

Returns a map with key/element
pairs initialized from the values in Source. If Capacity is 0, then the
map capacity is the length of Source; if Capacity is equal to or greater
than the length of Source, the map capacity is the specified value; otherwise,
the operation propagates Capacity_Error.

{*AI05-0160-1*}
{*AI05-0265-1*}
It is a bounded error to assign
from a bounded map object while tampering with elements [or cursors]
of that object is prohibited. Either Program_Error is raised by the assignment,
execution proceeds with the target object prohibiting tampering with
elements [or cursors], or execution proceeds normally.

{*AI05-0265-1*}
When a bounded map object *M* is finalized,
if tampering with cursors is prohibited for *M* other than due to
an assignment from another map, then execution is erroneous.

For each instance of Containers.Ordered_Maps and
each instance of Containers.Bounded_Ordered_Maps, if the two instances
meet the following conditions, then the output generated by the Map'Output
or Map'Write subprograms of either instance shall be readable by the
Map'Input or Map'Read of the other instance, respectively:

{*AI05-0184-1*}
{*AI05-0248-1*}
the Element_Type parameters of the two instances
are statically matching subtypes of the same type; and

{*AI05-0184-1*}
the output generated by Element_Type'Output or
Element_Type'Write is readable by Element_Type'Input or Element_Type'Read,
respectively (where Element_Type denotes the type of the two actual Element_Type
parameters); and

{*AI05-0184-1*}
the preceding two conditions also hold for the
Key_Type parameters of the instances.

{*AI05-0001-1*}
{*AI05-0269-1*}
Bounded ordered map objects should be implemented
without implicit pointers or dynamic allocation.

{*AI05-0001-1*}
The implementation advice for procedure Move to
minimize copying does not apply.

The generic package Containers.Bounded_Ordered_Maps
is new.
