public String getAuthority()

Description copied from interface: GrantedAuthority

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.

Specified by:

getAuthority in interface GrantedAuthority

Returns:

a representation of the granted authority (or null if the granted authority cannot be expressed as a String with sufficient precision).
