MsgMonitorOptions
The MsgMonitorOptions object contains a set of monitoring options that can be applied to the
message monitor points that OpenLNS is monitoring. Depending on how this object is
accessed, writing to this it may affect the monitoring options used for an entire monitor set,
or for an individual message tag monitor point.
The
MsgMonitorOptions object accessed through the MsgOptions property of a MonitorSet
object contains the default monitoring options for the monitor set. These are the default
options applied to all MsgMonitorPoint objects as they are added to the monitor set.
You can change the defaults an individual MsgMonitorPoint uses by writing to the
MsgMonitorOptions object accessed through the DefaultOptions property of that
MsgMonitorPoint object. This object contains the default options that will be used each time
the monitor set containing that particular MsgMonitorPoint object is opened. Note that this
only applies to message monitor points in permanent monitor sets. The CurrentOptions
properties of message monitor points in temporary monitor sets are not accessible, as
temporary monitor sets are only used in a singe client session.
You can change the monitoring options a
MsgMonitorPoint object will use for an active
monitoring session by writing to the MsgMonitorOptions object accessed through the
MsgMonitorPoint object’s CurrentOptions property. Changes made to the current options
take effect for the current session only, and are not stored persistently in memory.
Note that the
MsgMonitorOptions object contained within the MsgOptions property of a
monitor set (or the CurrentOptions properties of a monitor point) is not passed by reference.
If you acquire a MsgMonitorOptions object through any of these properties and modify it, you
must then explicitly assign the modified object back to the source property for the changes to
take effect.
The following table summarizes the MsgMonitorOptions object.
