public static DefaultAccessorNamingStrategy.BaseNameValidator forFirstNameRule(boolean allowLowerCaseFirstChar,
                                                                               boolean allowNonLetterFirstChar)
```
    Factory method to use for getting an instance with specified first-character restrictions, if any; or null if no checking is needed.
    
    Parameters:
    
    allowLowerCaseFirstChar - Whether base names that start with lower-case letter (like "a" or "b") are accepted as valid or not: consider difference between "setter-methods" setValue() and setvalue().
    
    allowNonLetterFirstChar - Whether base names that start with non-letter character (like "_" or number 1) are accepted as valid or not: consider difference between "setter-methods" setValue() and set_value().
    
    Returns:
    
    Validator instance to use, if any; null to indicate no additional rules applied (case when both arguments are false)
  - accept

public boolean accept(char firstChar,
                      String basename,
                      int offset)
```
