The modifications are to facilitate formal proofs by making it --- easier to express properties. - --- The modifications are: - --- A parameter for the container is added to every function reading the --- content of a container: Element, Next, Query_Element, Previous, Iterate, --- Has_Element, Reverse_Iterate. This change is motivated by the need --- to have cursors which are valid on different containers (typically a --- container C and its previous version C'Old) for expressing properties, --- which is not possible if cursors encapsulate an access to the underlying --- container. - --- There are two new functions: - --- function Left (Container : Vector; Position : Cursor) return Vector; --- function Right (Container : Vector; Position : Cursor) return Vector; - --- Left returns a container containing all elements preceding Position --- (excluded) in Container. Right returns a container containing all --- elements following Position (included) in Container. These two new --- functions are useful to express invariant properties in loops which --- iterate over containers. Left returns the part of the container already --- scanned and Right the part not scanned yet. - -private with Ada.Streams; -with Ada.Containers; -use Ada.Containers; - -generic - type Index_Type is range <>; - type Element_Type is private; - - with function "=" (Left, Right : Element_Type) return Boolean is <>; - -package Ada.Containers.Formal_Vectors is - pragma Pure; - - subtype Extended_Index is Index_Type'Base - range Index_Type'First - 1 .. - Index_Type'Min (Index_Type'Base'Last - 1, Index_Type'Last) + 1; - - -- ??? i don't think we can do this... - -- TODO: we need the ARG to either figure out how to declare this subtype, - -- or eliminate the requirement that it be present. - -- subtype Capacity_Subtype is Count_Type -- correct name??? - -- range 0 ..
