76 // Revision 1.3 2003/04/17 08:47:07 popovici
77 // Important functionality additions
78 // - Cflow specializers
79 // - Restructuring of the MethodCut, SetCut, ThrowCut, and GetCut (they are much smaller)
80 // - Transactional capabilities
81 // - Total refactoring of Specializer evaluation, which permits fine-grained distinction
82 // between static and dynamic specializers.
83 // - Functionality pulled up in abstract classes
84 // - Uniformization of advice methods patterns and names
85 //
86 // Revision 1.2 2003/03/04 11:27:01 popovici
87 // Important refactorization step (march):
88 // - removal of 'JoinPointEvents'; JoinPoints now have the same function as events
89 // - reimplementation of the JVMAIDebuggerAspectInterface (better performance, coding conventions, removal of ProseVM
90 // structures
