Class DefaultParanamer

java.lang.Object

com.thoughtworks.paranamer.DefaultParanamer

All Implemented Interfaces:

Paranamer

public class DefaultParanamer
extends Object
implements Paranamer

More recent Java versions have a means to access parameter names via reflection Only if -parameters is passed to javac though. This class now utilizes that. The former DefaultParanamer is now renamed to LegacyParanamer (uses QDox to attach more static field info to .class files) Really though in 2025, teams should not be using Paranamer at all.
