All Implemented Interfaces:

@Enhance
public class SafeVarargsPlugin
extends Plugin.ForElementMatcher
implements Plugin.Factory

A plugin that allows for adding a java.lang.SafeVarargs annotation even if compiled prior to Java 7 which introduces this annotation. As the annotation is not present on previous JVM versions, it is ignored at runtime for older JVM versions what makes this approach feasible.
