  16  * Test for UObject, currently only the classID.

  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.

 513      *
 514      * (Newsgroups: comp.std.c++, 27 Aug 97)
 515      *

 518      * > I do not completely understand how placement works on operator delete.
 519      * > ...
 520      * There is no delete-expression which will invoke a placement
 521      * form of operator delete. You can still call the function
 522      * explicitly. Example:
 523      * ...
 524      *     // destroy object and delete space manually
 525      *     p->~T();
 526      *     operator delete(p, 12);
 527      *
 528      * ... so that's what I am doing here.
