| getMask | | public int getMask()(Code) | | |
| getValidPermissions | | abstract public int[] getValidPermissions()(Code) | | Subclasses must indicate the permissions they support. Each base permission should be an integer with a
base 2. ie: the first permission is 2^^0 (1), the second permission is 2^^1 (2), the third permission is 2^^2
(4) etc. Each base permission should be exposed by the subclass as a public static final int. It
is further recommended that valid combinations of permissions are also exposed as public static final
ints.This method returns all permission integers that are allowed to be used together. This
must include any combinations of valid permissions. So if the permissions indicated by 2^^2 (4) and 2^^1
(2) can be used together, one of the integers returned by this method must be 6 (4 + 2). Otherwise attempts to
set the permission will be rejected, as the final resulting mask will be rejected.
Whilst it may seem unduly time onerous to return every valid permission combination, doing so
delivers maximum flexibility in ensuring ACLs only reflect logical combinations. For example, it would be
inappropriate to grant a "read" and "write" permission along with an "unrestricted" permission, as the latter
implies the former permissions.

| isPermitted | | protected boolean isPermitted(int maskToCheck, int permissionToCheck)(Code) | | |
| printPermissionsBlock | | abstract public String printPermissionsBlock(int i)(Code) | | Outputs the permissions in a human-friendly format. For example, this method may return "CR-D" to
indicate the passed integer permits create, permits read, does not permit update, and permits delete.
Parameters:
i - the integer containing the mask which should be printed the human-friend formatted block |
| printPermissionsBlock | | public String printPermissionsBlock()(Code) | | Outputs the permissions in human-friendly format for the current AbstractBasicAclEntry's
mask.
