Class NameRegistry

java.lang.Object
  org.springsource.loaded.NameRegistry

public class NameRegistry
extends java.lang.Object

Manages a mapping of names to numbers. The same number anywhere means the same name. This means that if some type a/b/C has been loaded in two places (by different classloaders), it will have the same number in both. Only one of those a/b/C types will be visible at the location in question, the tricky part could be working out which one (if classloaders are being naughty) but in theory the first time we get confused (due to finding the name twice), we can work out which one is right and use that mapping from then on.
