26 -- OBJECTIVE:
|
|
27 -- Check that assignment to an object of a (non-limited) controlled
|
|
28 -- type causes the Adjust operation of the type to be called.
|
|
29 -- Check that Adjust is called after copying the value of the
|
|
30 -- source expression to the target object.
|
|
31 --
|
|
32 -- Check that Adjust is called for all controlled components when
|
|
33 -- the containing object is assigned. (Test this for the cases
|
|
34 -- where the type of the containing object is controlled and
|
|
35 -- noncontrolled; test this for initialization as well as
|
|
36 -- assignment statements.)
|
|
37 --
|
|
38 -- Check that for an object of a controlled type with controlled
|
|
39 -- components, Adjust for each of the components is called before
|
|
40 -- the containing object is adjusted.
|
|
41 --
|
|
42 -- Check that an Adjust procedure for a Limited_Controlled type is
|
|
43 -- not called by the implementation.
|
|
44 --
|
|
45 -- TEST DESCRIPTION:
|
|
46 -- This test is loosely "derived" from C760001.
