16 * Test for UObject, currently only the classID.
17 *
18 * Usage
19 *   TESTCLASSID_NONE_DEFAULT(Foo)
20 *      --  Foo is expected to not support "poor man's RTTI".
21 *          Beginning with ICU 4.6, we only use compiler RTTI in new class hierarchies.
22 *
23 *   TESTCLASSID_NONE_CTOR(Foo, (1, 2, 3, status))
24 *      -- Combines TESTCLASSID_NONE_DEFAULT() and TESTCLASSID_CTOR().
25 *
26 *   TESTCLASSID_NONE_FACTORY(Foo, (1, 2, 3, status))
27 *      -- Combines TESTCLASSID_NONE_DEFAULT() and TESTCLASSID_FACTORY().
28 *
29 *   TESTCLASSID_ABSTRACT(Bar)
30 *      --  Bar is expected to be abstract. Only the static ID will be tested.
31 *
32 *   TESTCLASSID_DEFAULT(Foo)
33 *      --  Foo will be default-constructed.
34 *
35 *   TESTCLASSID_CTOR(Foo, (1, 2, 3, status))
36 *      -- Second argument is (parenthesized) constructor argument.
37 *          Will be called as:   new Foo ( 1, 2, 3, status)  [status is tested]
38 *
39 *   TESTCLASSID_FACTORY(Foo, fooCreateFunction(status) )
40 *      -- call fooCreateFunction.  'status' will be tested & reset
41 *
42 *   TESTCLASSID_FACTORY_HIDDEN(class, factory)
43 *      -- call factory.  Class is not available from a header.
44 *      'status' will be tested & reset. This only tests uniqueness.

533     * (Newsgroups: comp.std.c++, 27 Aug 97)

537     * > I do not completely understand how placement works on operator delete.
538     * > ...
539     * There is no delete-expression which will invoke a placement
540     * form of operator delete. You can still call the function
541     * explicitly. Example:
542     * ...
543     *     // destroy object and delete space manually
544     *     p->~T();
545     *     operator delete(p, 12);
546     *
547     * ... so that's what I am doing here.
