Modifier and Type	Method	Description
`java.lang.String`	`getAuthority()`	If the `GrantedAuthority` can be represented as a `String` and that `String` is sufficient in precision to be relied upon for an access control decision by an `AccessDecisionManager` (or delegate), this method should return such a `String`.

- Method Detail
  - getAuthority
```
java.lang.String getAuthority()
```
    If the GrantedAuthority can be represented as a String and that String is sufficient in precision to be relied upon for an access control decision by an AccessDecisionManager (or delegate), this method should return such a String.
    If the GrantedAuthority cannot be expressed with sufficient precision as a String, null should be returned. Returning null will require an AccessDecisionManager (or delegate) to specifically support the GrantedAuthority implementation, so returning null should be avoided unless actually required.
    
    Returns:
    
    a representation of the granted authority (or null if the granted authority cannot be expressed as a String with sufficient precision).
