TopPublic Methods
| | Name | Description |
|---|
 | ChangeBrowsePosition |
This method provides a way to move up or down relative to the current position,
or directly to a given position in a hierarchy.
|
| Dispose |
Release the browser COM object. This method MUST be executed before the client terminates for
the OPC server to be released.
|
| GetBranchPosition |
This function provides the current browse position in the hierarchy.
|
| GetEnum |
This function returns a string array with all enumerated leaves, branches, or
ItemIDs, depending on the browse type requested. Whether a branch is an ItemID is
undetermined and may be server dependent. The members of the array set will be
determined by the position of the browser in the server address space and the value of
the filters when the browser interface was created. If no ItemIDs pass the filter
criteria, the array is empty. Thus, a server which has a flat namespace would always
return an empty array when asked for a list of branches, and it would return the same
list whether it was asked for leafs or ItemIDs, since all of its Items are, by
definition, leafs.
|
| GetItemID |
This function provides a way to get a fully qualified item identification. This is required
since the browsing functions return only the components or tokens that make up an ItemID and
do not return the delimiters used to separate those tokens.
