很神奇吧, ar是怎么根据文件(强调一下,是根据文件,而不是硬编码)判断需要创建什么类的.它大概有这么几个步骤:1. 因为DECLARE_SERIAL重载了>>操作符,所以可以保证是调用CMessg类的>>函数.2. >>函数实际上调用的是ar的ReadObject(CRuntimeClass*)函数3. ReadObject首先从文件中读取类判断信息(可能是...
This version adds a parameterless constructor to the struct. The parameterless constructor must invoke the primary constructor, so that all the primary constructor parameters are initialized.In the previous example, the primary constructor properties are accessed in a method. Therefore the compiler ...
