setPointSecurity
setPointSecurity — sets the security attributes of a Cascade DataHub
point.
Syntax
For C++:
ST_STATUS setPointSecurity( | CDataHubPoint& | point, |
| | int | security); |
ST_STATUS setPointSecurity( | LPCTSTR | pointname, |
| | int | security); |
For Java and C#:
Exception setPointSecurity( | CDataHubPoint& | point, |
| | int | security); |
Exception setPointSecurity( | String | pointname, |
| | int | security); |
Parameters
- point
- A
DataHubPoint object. The name
and security members must be valid.
- pointname
- The name of the point.
- security
- The new security level to which the DataHub
point will be set.
Returns
For C++:
- ST_OK if the command was
successfully sent to the DataHub. Since the command
is sent asynchronously, the actual success or failure of
the command must be determined through the onSuccess
or onError
message handlers.
- ST_NO_TASK if a connection to
the DataHub does not exist.
- ST_ERROR if the connection
socket is unable to send the message.
Description
This method sets the security
attributes of a DataHub point. An update to a DataHub point
will be rejected unless the security level associated with the new
point value is greater than or equal to the corresponding
DataHub point. The default DataHub point security level is
0.
