There's one CRuntimeClass structure for each CObject-derived class. The structure members are as follows:LPCSTR m_lpszClassName A null-terminated string containing the ASCII class name. int m_nObjectSize The size of the object, in bytes. If the object has data members that point to ...

由上图可以看出,元类的isa都指向根元类(Root Meta Class),即元类都是根元类的实例。 而根元类(Root Meta Class)的isa则指向自己,这样就不会无休止的关联下去了。图中同样展示类和元类的继承关系,非常清晰易懂。 类的实例数据结构 在Objective-C 中类的实例的数据结构是定义在struct objc_object 中(objc...

Setting the thread stack size to a value larger than the default may be necessary for some parallelized code. Sometimes the compiler may generate a warning message that indicates a bigger stack size is needed. However, it may not be possible to know just how large to set it, except by tri...
抽象语法树(abstract syntax code,AST)是源代码的抽象语法结构的树状表示,树上的每个节点都表示源代码中的一种结构,之所以说是抽象的,是因为抽象语法树并不会表示出真实语法出现的每一个细节,比如说,嵌套括号被隐含在树的结构中,并没有以节点的形式呈现。抽象语法树并不依赖于源语言的语法,也就是说语法分析阶段所...
