Public Methods
| Name | Description | |
|---|---|---|
 | BrowseOPCAreas | Return a string array with a list of Areas as determined by the passed parameters. The position from which the browse is done can be set via the ChangeBrowsePosition.{br/> The returned enumerator may be empty if no Areas or Sources satisfied the filter constraints. The strings returned by the enumerator represent the Areas or Sources contained in the current level. They do not include ?? and delimiter or “parent” names. Clients are allowed to create and hold multiple enumerators in order to maintain more than one “browse position” at a time. Changing the browse position in one enumerator will not affect any other enumerator the client has created. The client must release each enumerator when finished with it. |
| ChangeBrowsePosition | Provides a way to move ‘up’ or ‘down’ in a hierarchical space from the current position, or a way to move to a specific position in the area space tree. The target string must represent an area, rather than a source. An error is returned if the passed string does not represent an area. Moving ‘up’ from the ‘root’ shall return E_FAIL. |
| GetQualifiedAreaName | Provides a mechanism to assemble a fully qualified Area name in a hierarchical space. This is required since at each point one is browsing just the names below the current node. The server must return strings that can be added to the areaList for the EventSubscriptionMgt::SetFilter method, and can be used in the EventAreaBrowser.ChangeBrowsePosition method to move to a specific place in the process area space tree. |
| GetQualifiedSourceName | Provides a mechanism to assemble a fully qualified Source name in a hierarchical space. This is required since at each point one is browsing just the names below the current node. The server must return strings that can be added to sources for the EventServer.EnableConditionBySource method. |
