C++ Plugin Architecture Types

There are several types of plugin system architectures in C++. Here are some common ones:

Dynamic Linking

This architecture uses shared libraries to dynamically load and unload plugins at runtime.
The plugins are implemented as shared libraries (DLLs on Windows, .so files on Linux), and the plugin manager loads them using dynamic linking functions like dlopen() and GetProcAddress().
This architecture is widely used on both Windows and Unix-like systems.
It's commonly used in multimedia applications, web browsers, and operating systems.

This architecture uses static libraries to link the plugins to the main application at compile time.
The plugins are implemented as static libraries that are linked to the main executable using the linker.
This architecture is less flexible than dynamic linking, but it has better performance and can be used on systems that don't support dynamic linking.
It's commonly used in embedded systems, game engines, and high-performance computing applications.

This architecture uses a scripting language like Lua or Python to implement the plugins.
The plugins are implemented as scripts that are executed by an embedded interpreter in the main application.
This architecture is easy to use and allows for rapid prototyping, but it can be slower than native code and may require more memory.
It's commonly used in game engines, desktop applications, and web applications.

This architecture uses the Component Object Model (COM) or Object Linking and Embedding (OLE) to implement the plugins.
The plugins are implemented as COM/OLE objects that can be loaded and instantiated by the plugin manager.
This architecture is widely used on Windows systems, but it can be complex and difficult to implement.
It's commonly used in Office applications, database applications, and web browsers.

This architecture uses reflection to dynamically load and instantiate plugins.
The plugins are implemented as C++ classes that can be instantiated using a factory method or a reflection library like Boost. Reflection.
This architecture is flexible and easy to use, but it can be slower than native code and may require more memory.
It's commonly used in frameworks, libraries, and middleware.
