DCD (Dead Code Detector)

DCD (Dead Code Detector) is a handy tool that helps you quickly find any parts of code in your apps that you don’t really need. If you’re tired of dealing with cluttered code, DCD is here to help!

How DCD Works

All you have to do is provide a directory of compiled classes, or even a jar or war file right in the user interface. DCD will then list out the potential dead code for you. This includes all sorts of things like private, package-private, protected, and public code. Plus, it can spot unread local variables, self-assignments, toString calls on Strings, and other pointless initializations.

Understanding Dead Code Detection

Keep in mind that what DCD finds are just suspects. It can’t tell if something is actually being used through reflection or other means. So it’s always good to chat with someone who knows your application inside out before getting too upset about what DCD flags.

Fast and Efficient Searches

The search process is super quick—around 2000 classes per second when working with warmed-up files! It uses static analysis on the compiled classes without needing to run the application or load any classes.

Using ASM Library

DCD relies on the open-source ASM library from ObjectWeb/OW2 to perform its magic. This means it’s both efficient and effective at detecting dead code.
