2009年12月10日 · Compile time polymorphism is a term that refers to C++ template programming. For example, at compile time you determine the actual type of a std::vector by what it contains: std::vector <int> vi; std::vector <std::string> vs; …

2023年9月4日 · For ad-hoc polymorphism there's also the question of whether the resolution of implementation code happens at run-time (dynamic) or compile-time (static). Method overloading is generally static, and method overriding is dynamic. This is where the terms static/compile-time polymorphism and dynamic/run-time polymorphism come from.

2012年12月24日 · The polymorphism in which compiler identifies which polymorphic form to execute at runtime but not at compile time is called as runtime polymorphism or late binding. Advantage of late binding is flexibility and disadvantage is execution will be slow as compiler has to get the information about the method to execute at runtime.

2013年12月26日 · Static polymorphism (Compile-time Polymorphism) Static Polymorphism decides which method to execute during compile time. Method Overloading is an example of static polymorphism, and it is requred to happens static polymorphism. Static Polymorphism achieved through static binding. Static Polymorphism happens in the same class.

2012年4月30日 · They are hinting at method overloading, which is sometimes referred to as a compile-time polymorphism. Indeed, method overloading lets you invoke different pieces of code based on the types of objects passed in as parameters. Overloads are resolved at compile time, so the mechanism of overloading could be thought of as a compile-time polymorphism.

2012年5月11日 · Compile-time polymorphism is provided by templates in C++. A template function or class can take any type which conforms to a prototype, usually called a "concept". Unlike base classes and virtual functions, the prototype is implicit : the prototype is defined only by how the type is used by the template function/class.

2017年4月14日 · Essentially, polymorphism refers to the feature that a method is not executed by a fixed method implementation that is defined at compile time, but rather there is a lookup at runtime which method implementation is chosen to execute the call.

2015年9月8日 · The question conflates compile-time with static binding and run-time with dynamic binding. Static binding happens at compile time; dynamic binding happens at runtime. Now, when you write. myclass m= new thisclass(); m.here(18); what happens at compile-time is the resolution of the method signature: you are calling here(int) and that choice is ...

We can use compile-time polymorphism in many situations. And because it gives us compile-time checks instead of possible run-time errors related to runtime polymorphism, and well as some (usually insignificant, however) performance benefit, it looks nowadays most widely use libraries prefer compile-time polymorhism over run-time one.

2012年1月22日 · If the enum is used for something else (that the compiler cannot resolve for you), you can still pass it around and rewrite the helper to dispatch on the enum rather than the type of the argument and you will have to rewrite the code to have the enum value as a compile time constant (simplest: pass it as template argument to algo). In this case ...
