Topics Hierarchy editor

The Topics Hierarchy editor is the default editor that is provided by the Broker Administration perspective for managing the publish/subscribe topic hierarchy. Use this editor to create, modify, and delete topics, or to define or modify your topic Access Control Lists (ACLs).

The Topics Hierarchy editor is launched in the editor area of the Broker Administration perspective when you double-click Topics in the Domains view.

If you are not connected to a domain, an attempt to do so is made before opening the editor. During this attempt, if you click Cancel, the connection that is in progress stops and the domain returns to its initial unconnected state.

In the editor view, use the Topic/Users and User/Topics buttons to determine whether you see a list of topics or a list of users in the left-hand part of the editor area.

If you click Topic/Users, the left-hand part of the editor area contains a list of the topics. Click on a topic to see in the right-hand part of the editor area the ACL for the topic that you selected.

If you click User/Topics, the left-hand part of the editor area contains a list of the groups and users. Click on a group or user to see in the right-hand part of the editor area the ACL for the topics that are available to the group or user that you selected.

When the editor is launched, an Outline view is also shown that lists the topics and principals (groups and users).

Either the outline view or the editor view can be used to select what is shown in the right-hand part of the editor area. The behavior varies depending on whether Topic/Users or User/Topics is selected.

If Topic/Users is selected, the following happens:
  • If you select a topic in the Outline view, the corresponding topic is selected in the Topics tree.
  • If you select a user or group in the Outline view, the corresponding group or user is selected in the Topic ACL table.
  • If you select a topic in the Topics tree, the corresponding topic is selected in the Outline view.
  • If you select a group or user in the Topic ACL table, the corresponding group or user is selected in the Outline view.
If User/Topics is selected, the following happens:
  • If you select a topic in the Outline view, the corresponding topic is selected in the User ACL table.
  • If you select a user or group in the Outline view, the corresponding group or user is selected in the Users tree.
  • If you select a user or group in the Users tree, the corresponding user or group is selected in the Outline view.
  • If you select a topic in the User ACL view, the corresponding topic is selected in the Outline view.

The Outline view reacts to changes made in the editor area; for example when a topic is created or removed.
