The Active Object Design Pattern is a concurrency pattern used to separate method invocation from method execution, allowing asynchronous and non-blocking behavior. It is particularly useful in C++ for handling concurrent tasks efficiently without blocking the main execution thread. In this article, we'll explore the Active Object Design Pattern and demonstrate its real-time application with a practical example in C++.
Understanding the Active Object Design Pattern:
The Active Object Design Pattern decouples method invocation from execution by using a message queue to buffer method calls. The active object, which contains the methods to be executed, processes the message queue in a separate thread. This design ensures that the main thread is not blocked, and multiple tasks can be executed concurrently.
