Active Object [AO]

The active object design pattern decouples method execution from method invocation for objects that each reside in their own thread of control. Typically, an active object is constructed using an internal thread and a queue of operations or events that will be executed on the active object’s thread. The goal is to enable concurrency using asynchronous invocation, and to eliminate the need for an object to worry about managing threading details itself: that’s all taken care of under the hood.

Looks like the link for “Know When to Use Active Objects Instead of a Mutex” is broken. The new link is: https://www.state-machine.com/doc/Sutter2010b.pdf
