Obsolete Habits
In the many years of developing OpenOffice.org and its antecessors some habits have been developed that are now obsolete. There are better alternatives today that should always be preferred.
Rules
PreferredTypes
Previously: “solar” types where used and various string implementations. For lists and vectors self-made types were implemented, often by macros.
Now: Use sal-Types instead of “solar” types. Use rtl:O[U]String[Buffer] classes instead of any other string implementation. Use STL containers instead of DECLARE_LIST and other self-made containers.
AvoidHeapAlloc
Previously: Heap allocation was preferred to stack allocation in function bodies, because stack size was small.
Now: Don't fetch local data or objects from the heap, if they are not of user-defined size. Allocation from the stack is faster.
NoOldMacros
Previously: TRY and CATCH where used.
Now: Use “try” and “catch”.
