For example, if I do scala> val a = Set(1,2,3) a: scala.collection.immutable.Set[Int] = Set(1, 2, 3)
I\'m micro-optimizing code for identifying object types. I assume I can use the following for checking whether two objects instantiated in the same module have identical types:
If I call typeid and retrieve the address of returned type_info: const type_info* info = &( typeid( Something ) );
I have a set of polymorphic C++ classes and they are all instantiated by the same module (Windows DLL). Now having two pointers to such classes and having called typeid:
What, if any, c++ constructs are there for listing the ancestors of a class at runtime? Basically, I have a class which stores a pointer to any object, including possibly a primitive type (somewhat
There are many reasons not to use typeid.Other than for using members of type_info (implementation defined behavior), 开发者_C百科it is usually (always?) possible to provide similar functionality usin
I tried to create a container for posible metadata that can be attached to my objects. I can guarantee that there will be at most one object af each kind attached to my class but there is no limit for
Is it generally considered bad practice to use typeid in production code? Also, I noticed typeid returns type_info, which inc开发者_Python百科ludes some metadata (such as a string with the type\'s nam
The print statement 开发者_开发知识库in the constructor\'s definition doesn\'t get printed, isn\'t the constructor calling correct in main? I know I am missing some point here, please point out.
I found that dynamic_cast didn\'t work 开发者_C百科in a situation where I expected it to, and looking at the typeid of the objects at runtime has made the situation even less clear. I just want a cast
