RequireValidRevisedQueueSize Property (UAClientMonitoredItemParameters)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Engine Namespace > UAClientMonitoredItemParameters Class : RequireValidRevisedQueueSize Property
Enforce that the server provides a valid revised queue size.
Syntax
'Declaration
 
<DefaultValueAttribute(False)>
Public Property RequireValidRevisedQueueSize As Boolean
'Usage
 
Dim instance As UAClientMonitoredItemParameters
Dim value As Boolean
 
instance.RequireValidRevisedQueueSize = value
 
value = instance.RequireValidRevisedQueueSize
[DefaultValue(false)]
public bool RequireValidRevisedQueueSize {get; set;}
[DefaultValue(false)]
public:
property bool RequireValidRevisedQueueSize {
   bool get();
   void set (    bool value);
}
Remarks

Many servers fail in this respect, providing 0 instead of 1 for data monitored items with default queue size.

In order to obtain or modify this parameter, in the default state (when OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated equals to false), access UAClientAdaptableParameters.MonitoredItemParameters property of static OpcLabs.EasyOpc.UA.EasyUAClientCore.AdaptableParameters. If you have set OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated to true, you need to access UAClientAdaptableParameters.MonitoredItemParameters property of OpcLabs.EasyOpc.UA.EasyUAClientCore.IsolatedParameters.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
