        Description copied from class: ClassVisitor
        Visits information about an inner class. This inner class is not necessarily a member of the class being visited. More precisely, every class or interface C which is referenced by this class and which is not a package member must be visited with this method. This class must reference its nested class or interface members, and its enclosing class, if any. See the JVMS 4.7.6 section for more details.
        Overrides:
        visitInnerClass in class ClassVisitor
        Parameters:
        name - the internal name of C (see Type.getInternalName()).
        outerName - the internal name of the class or interface C is a member of (see Type.getInternalName()). Must be null if C is not the member of a class or interface (e.g. for local or anonymous classes).
        innerName - the (simple) name of C. Must be null for anonymous inner classes.
        access - the access flags of C originally declared in the source code from which this class was compiled.
