reservedClassNames

private final HashSet<String> reservedClassNames

generatedClasses

private final LoadingCache<AbstractClassGenerator,Object,Object> generatedClasses

AbstractClassGenerator here holds "cache key" (e.g. Enhancer configuration), and the value is the generated class plus some additional values (see AbstractClassGenerator.unwrapCachedValue(Object).

The generated classes can be reused as long as their classloader is reachable.

Note: the only way to access a class is to find it through generatedClasses cache, thus the key should not expire as long as the class itself is alive (its classloader is alive).

classLoader

private final WeakReference<ClassLoader> classLoader

Note: ClassLoaderData object is stored as a value of WeakHashMap<ClassLoader, ...> thus this classLoader reference should be weak otherwise it would make classLoader strongly reachable and alive forever. Reference queue is not required since the cleanup is handled by WeakHashMap.

GET_KEY

private static final Function<AbstractClassGenerator,Object> GET_KEY
