13 * Purpose: implements methods of "template" class declared in *
14 * DECLARE_OBJARRAY macro and which couldn't be implemented inline *
15 * (because they need the full definition of type T in scope) *
16 * *
17 * Usage: 1) #include dynarray.h *
18 * 2) WX_DECLARE_OBJARRAY *
19 * 3) #include arrimpl.cpp *
20 * 4) WX_DEFINE_OBJARRAY *
