This is not about \"When VTABLE is created?\". Rather, when the VPTR should be initialized? Is it at the beginning/end of the constructor or before/after the constructor?[详细]

First of all, I want to make myself clear that I do understand that there is no notion of vtables and vptrs in the C++ standard. However I think that virtually all implementations implement the virtua[详细]

While debugging one of the p开发者_如何学Gorogram\'s core dump I came across the scenario where its contained object which is polymorphic loses its VPTr and I can see its pointing to NULL.[详细]

I am little confused about vptr and representation of objects in the memory, and hope you can help me understand the matter better.[详细]
2023-01-09 04:48 分类：问答Are there cases where a class declares virtual methods and the compiler does not need to use a vptr?
I was wondering if there is a possible optimization where the compiler does not need to assign a vptr to an instantiated object even though the object\'s type is a class with virtual methods.[详细]
