Boost.Signals

Boost.Signals is a C++ library that facilitates the implementation of the observer pattern, allowing objects to communicate through signals and slots. Think of signals as events or notifications that can be emitted by one part of a program, and slots as functions or handlers that respond to these signals. When a signal is emitted, all connected slots are automatically invoked. This system promotes loose coupling between components, making software more modular and flexible. Boost.Signals simplifies managing these connections, enabling developers to create responsive, event-driven applications without tightly integrating different parts of the code.
