public String getPattern()
Permission
String
representing this permission.
Implementations are free to format the pattern as they see fit, although under no circumstances may
Permission.RESERVED_OFF
or Permission.RESERVED_ON
be used within the pattern. An exemption is in the case of
Permission.RESERVED_OFF
which is used to denote a bit that is off (clear).
Implementations may also elect to use Permission.RESERVED_ON
internally for computation purposes,
although this method may not return any String
containing Permission.RESERVED_ON
.
The returned String must be 32 characters in length.
This method is only used for user interface and logging purposes. It is not used in any permission calculations. Therefore, duplication of characters within the output is permitted.
