```
- Method Detail
  - name
```
public static java.lang.String name(int token)
```
    Returns a name for the token. If Rhino is compiled with certain hardcoded debugging flags in this file, it calls #typeToName; otherwise it returns a string whose value is the token number.
  - typeToName
```
public static java.lang.String typeToName(int token)
```
    Always returns a human-readable string for the token name. For instance, FINALLY has the name "FINALLY".
    
    Parameters:
    
    token - the token code
    
    Returns:
    
    the actual name for the token code
  - keywordToName
```
public static java.lang.String keywordToName(int token)
```
    Convert a keyword token to a name string for use with the Context.FEATURE_RESERVED_KEYWORD_AS_IDENTIFIER feature.
    
    Parameters:
    
    token - A token
    
    Returns:
    
    the corresponding name string
  - isValidToken
```
public static boolean isValidToken(int code)
```
    Return true if the passed code is a valid Token constant.
    
    Parameters:
    
    code - a potential token code
    
    Returns:
    
    true if it's a known token
