The classes + in this mini framework allows the Map interface to be used + without caring about the specific Map implementation being used. + There is the class hierarchy of the framework: + + forwards + ACE_Iterator --------> ACE_Iterator_Impl (abstract) + + ACE_Iterator_Impl is subclassed by: + + - ACE_Map_Impl_Iterator_Adapter<IMPLEMENTATION> + - ACE_Active_Map_Manager_Iterator_Adapter + - ACE_Hash_Map_Manager_Ex_Iterator_Adapter + - ACE_Map_Manager_Iterator_Adapter + + forwards + ACE_Reverse_Iterator --------> ACE_Reverse_Iterator_Impl (abstract) + + ACE_Reverse_Iterator_Impl is subclassed by: + + - ACE_Map_Impl_Reverse_Iterator_Adapter<IMPLEMENTATION> + - ACE_Active_Map_Manager_Reverse_Iterator_Adapter + - ACE_Hash_Map_Manager_Ex_Reverse_Iterator_Adapter + - ACE_Map_Manager_Reverse_Iterator_Adapter + + ACE_Map is subclassed by: + + - ACE_Map_Impl<IMPLEMENTATION> + - ACE_Active_Map_Manager_Adapter + - ACE_Hash_Map_Manager_Edapter + - ACE_Map_Manager_Adapter + + Also included in the framework is a Key Generator class and a + Key Adapter class. The Key Generator class is used by some map + adapters to generate keys since the maps they adapt do not + generate keys. The Key Adapter class is used by the active map + adapter to allow encoding and decoding of active keys into user + keys. + + Note that the iterators use the bridge pattern while the map + class uses an abstract base class based inheritance approach. + The reason for this is that STL containers return the iterators + by value. An abstract base class cannot be returned by value. + + An alternative design would be to add an abstract base class + that the ACE maps would derive fro Unfortunately, this would + break many things including the ability to add these maps to + shared memory and explicit template instantiations. + + This mini framework would have been idle to apply the external + polymorphism pattern. However, the ACE map classes are + different enough that adaption was necessary. This turned out + to be a blessing in disguise since I was able to add extra + common functionality such as the key generator and key adapter + to the map adapters. I did add the external polymorphic + subclasses to the framework for future use. + + The classes in this framework are as close STL containers as I + would dare to make them ;) Thanks to Carlos for helping design + them. + + * tests/Map_Test: New test to illustrate and test the workings of + the new ACE Map classes. There are two aspect to this test: + (a) functionality testing includes testing the iterators and + various operations, and (b) performance testing to compare the + relative performance of the maps. + + * ace/Pair: Added new Pair class to ACE that holds instances of + the template arguments. Also, added a Reference_Pair class that + only hold references of the template arguments. + + * ace/Hash_Map_Manager_T.* (ACE_Hash_Map_Manager_Ex): + * ace/Map_Manager.* (Map_Manager): + Added new rebind() methods to make interface compatible with + other maps. Also, fixed the constness of some functions. + + * ace/Hash_Map_Manager.h: Fixed order of inclusion of template + code. + + * ace/Active_Map_Manager_T.h (ACE_Active_Map_Manager): Added new + versions of bind, find, and unbind to reduce the number of data + copies. + + * ace/Active_Map_Manager.h (ACE_Active_Map_Manager_Key): Added the + ability for the active key to encode and decode into and out of + a data stream. This relieves the developer from concerning + herself about the internal structure of the active key. + + * ace/config-win32-common.h: Define WIN32 if not already defined. + + * tests/SString_Test.cpp: Added testing for substring creation and + comparisons. + + * ace/OS.h (ACE_dynamic_cast_*_ptr and ACE_dynamic_cast_*_ref): + Added new macros to handle casting of template class. + + * tests/test_config.h: Removed global KEY class that was not being + used anymore anyway. + Fri Feb 05 21:12:56 1999 Douglas C. Schmidt <schmidt@cs.wustl.edu> * ACE version 4.6.20 released. |
