```
    Description copied from interface: CompilerPass
    
    Process the JS with root node root. Can modify the contents of each Node tree
    
    Specified by:
    
    process in interface CompilerPass
    
    Parameters:
    
    externs - Top of external JS tree
    
    root - Top of JS tree
  - hotSwapScript
```
public void hotSwapScript(Node scriptRoot,
                          Node originalRoot)
```
    Description copied from interface: HotSwapCompilerPass
    
    Process the JS with root node root. This is supposed to be significantly faster compared to corresponding full-compiler passes.
    
    Specified by:
    
    hotSwapScript in interface HotSwapCompilerPass
    
    Parameters:
    
    scriptRoot - Root node corresponding to the file that is modified, should be of type Token.SCRIPT.
    
    originalRoot - Root node corresponding to the original version of the file that is modified. Should be of type token.SCRIPT.
