ACL
for Nirvana P2P services
When you have connected to a realm, and have a reference
to an nRealmNode
object, and an nServiceNode
that corresponds to a p2p service, you can access the
node's acl object. This object contains a list of nServiceACLEntry
objects that represent a subject and a set permissions
for various operations on a p2p service.
You can also, add, delete and modify acl entry objects.
To obtain the queue acl object, simply call the following
method from a realm node:
|
|
nServiceNode service = realm.findNode("nirvana-shell");
nACL acl = service.getACLs();
Once you have the acl object, you can then add, remove
or modify acl entries:
nServiceACLEntry
To find a specific acl entry from the service acl,
you can search the acl using the subject. For example,
if I wished to change the default permissions for the
*@* subject (i.e. the default permission for the service),
I could use the following code:
nServiceACLEntry entry = acl.find("*@*");
entry.setFullPrivileges(false);
acl.replace(entry);
service.setACLs(acl);
which would set the full privileges flag to false for
the default subject.
