As mentioned inthis comment we have similar implementations for determining the fully qualified names of classes, especially for anonymous classes and local classes.

We should try to unify the implementations. On first sight, it looks like it should be part of the node (e.g. ClassOrInterfaceDeclaration). Given, that we - thanks to the metrics efforts - have agetQualifiedName() method, we probably should reuse this in the SymbolTable and TypeResolution, too.
