This is enough to check whether the object is + from a derived type or not. A slow dynamic_cast has only to be performed if it + is derived, and the C++ vfunc needs to be called. + * glib/glibmm/objectbase.h: This requires ObjectBase::is_derived_ to be public, + because it is called on a ObjectBase* rather than the actual type. + This causes a slight speed up of vfuncs and default signal handler invokation. + + Also added commented-out inline versions of ObjectBase::_get_current_wrapper() and + ObjectBase::is_derived(), which could be used in the generated code if we find + that this has significant performance benefits. Note that these methods must be + additional to the non-inline methods, because inline methods are not usually exported in the + shared library. + 2.12.7: 2007-03-03 Murray Cumming <murrayc@murrayc.com> |
