What is the equivalent of Windows' COM technology in Linux systems?
In Linux systems, the equivalent technology to Windows' Component Object Model (COM) is called D-Bus (Desktop Bus). D-Bus is a message bus system that provides interprocess communication (IPC) and object communication between applications and processes on a Linux desktop environment. It allows different software components to communicate and exchange messages with each other.
D-Bus provides features similar to COM, such as:
Message passing: Applications can send messages to each other, allowing them to interact and exchange information.
Object-oriented communication: D-Bus supports object-oriented communication where applications expose objects and interfaces that other applications can access and invoke methods on.
Service discovery: Applications can publish their services on the D-Bus bus, allowing other applications to discover and utilize them.
Event notification: D-Bus supports the publishing and subscribing to events, enabling applications to send notifications and subscribe to receive notifications from other applications.
D-Bus is widely used in Linux desktop environments, such as GNOME and KDE, to enable communication between various components of the desktop environment. It is a fundamental technology for building modular and interoperable Linux applications.
It's important to note that while D-Bus serves as the de facto standard IPC mechanism on Linux, there are other IPC technologies available, such as CORBA (Common Object Request Broker Architecture) and XPCOM (Cross-Platform Component Object Model), which are not as widely adopted as D-Bus.
