All Implemented Interfaces:

Navigator<NType,NClass,java.lang.Void,java.lang.Void>
```
public final class NavigatorImpl
extends java.lang.Object
implements Navigator<NType,NClass,java.lang.Void,java.lang.Void>
```
Navigator implementation for XJC. Most of the Navigator methods are used for parsing the model, which doesn't happen in XJC. So Most of the methods aren't really implemented. Implementations should be filled in as needed.

```
public boolean isInnerClass(NClass clazz)
```
    Description copied from interface: Navigator
