In all cases, a +-- check is made that Constraint_Error is raised if the tag of the +-- operand does not identify a specific type covered by or descended +-- from the target type, and not raised otherwise. +-- +-- For the cases where the view conversion is the left side of an +-- assignment statement, and Constraint_Error should not be raised, +-- an additional check is made that only the corresponding portion +-- of the operand is updated by the assignment. For example: +-- +-- type T is tagged record +-- C1 : Integer := 0; +-- end record; +-- +-- type DT is new T with record +-- C2 : Integer := 0; +-- end record; +-- +-- A : T := (C1 => 5); +-- B : DT := (C1 => 0, C2 => 10); +-- CWDT : T'Class := B; +-- +-- T(CWDT) := A; -- Updates component C1; C2 remains unchanged. +-- -- Value of CWDT is (C1 => 5, C2 => 10). +-- +-- +-- CHANGE HISTORY: +-- 31 Jul 95 SAIC Initial prerelease version. +-- 22 Apr 96 SAIC ACVC 2.1: Added a check for correct tag. +-- 08 Sep 96 SAIC ACVC 2.1: Modified Report.Test. +-- +--!
