When you have connected to a realm, and have a reference to an nRealmNode object (see nRealmNode), and an nLeafNode (see nLeafNode (Channels and Queues)) that corresponds to a queue, you can access the node's ACL object. This object contains a list of nChannelACLEntry objects that represent a subject and a set permissions for various operations on a queue.

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:

Java, C#:

C++:

Once you have the acl object, you can then add, remove or modify acl entries:

To find a specific ACL entry from the queue 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 queue), I could use the following code:

Java, C#:

C++:

which would set the full privileges flag to false for the default subject.
