package com.mebigfatguy.fbcontrib.detect;
looks for fields in serializable classes that are defined as both final and transient. As a transient field is not initialized when streamed, and is not initialized in a constructor, it will remain null because it is defined final.
public class NonFunctionalField extends PreorderVisitor implements Detector {
	private static JavaClass serializableClass;
	static {
		try {
			 = Repository.lookupClass("java/io/Serializable");
catch (ClassNotFoundException cnfe) {
		}
	}
constructs a NFF detector given the reporter to report bugs on

Parameters:
bugReporter the sync of bug reports
	public NonFunctionalField(BugReporter bugReporter) {
		this. = bugReporter;
	}

checks to see if the class is Serializable, then looks for fields that are both final and transient

Parameters:
classContext the context object of the currently parsed class
	public void visitClassContext(ClassContext classContext) {
		try {
			JavaClass cls = classContext.getJavaClass();
			if (( != null) && (cls.implementationOf())) {
				Field[] fields = cls.getFields();
				for (Field f : fields) {
					if (!f.isStatic() && f.isFinal() && f.isTransient()) {
						           .addClass(this)
						           .addField(cls.getClassName(), f.getName(), f.getSignature(), f.getAccessFlags()));
					}
				}
			}
catch (ClassNotFoundException cnfe) {
		}
	}
	public void report() {
	}
