Exception(例外) If your implementation provided a really slow dynamic_cast, you may have to use a workaround. However, all workarounds that cannot be statically resolved involve explicit casting (typically static_cast) and are error-prone. You will basically be crafting your own special-purpose ...

Message has an enum field called MessageType, which is initalized in the derived class' constructor to the correct value, so the recipent just uses a switch-case during the process. My question is that is it worth the redundancy? dynamic_cast is slower than the integer check but every time...
I know about dynamic_cast but seriously wondering when to use that? Why not ALWAYS add the appropriate function to the base class and always have access to the function you need? Does this have any performance aspects? I wrote a small example to illustrate this. Without the pure virtual fun...
However, it is more general than the other listed methods (because you can cast to intermediate types), and it doesn't use extra space in your binary like a bunch of virtual functions do. But it's not so advisable in performance-critical code....

You can try 8.0.0, but you'd need to verify that your application still meets your performance goals. Up 0 True Down Markus Moll 9 年多前 in reply to Archaeologist Expert 1820 points Archaeologist 说: DM6435 has a C64x+ CPU, which is fully supported by C6000 co...
Hi, Now, I have some problem with ccs or evm6474. //test_dynamic.cpp #include <iostream> using namespace std; struct B1{ virtual ~B1(){} }; struct B2
