Method Detail

calculatePermissions

public static int calculatePermissions(int privs,
                                       int parentPrivs,
                                       boolean isAllow,
                                       boolean protectsPolicy)

Build the permissions granted by evaluating the given privileges. If protectesPolicy is true read and write permission are only granted if the corresponding ac-privilege is present.

Parameters:

privs - The privileges granted on the Node itself (for properties the ACL of the direct ancestor).

parentPrivs - The privileges granted on the parent of the Node. Not relevant for properties since it only is used to determine permissions on a Node (add_child_nodes, remove_child_nodes).

isAllow -

protectsPolicy -

Returns:

the permissions granted evaluating the given privileges.

diff

public static int diff(int permissions,
                       int otherPermissions)

Returns those bits from permissions that are not present in the otherPermissions, i.e. subtracts the other permissions from permissions.
If the specified otherBits do not intersect with bits, bits are returned.
If bits is included otherBits, NONE is returned.

Parameters:

permissions -

otherPermissions -

Returns:

the differences of the 2 permissions or NONE.
