OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.ComTypes Namespace > _UASubscriptionParameters Interface : Priority Property
Indicates the relative priority of the Subscription (0 = no special priority required).
Syntax
'Declaration
 
Property Priority As Byte
'Usage
 
Dim instance As _UASubscriptionParameters
Dim value As Byte
 
instance.Priority = value
 
value = instance.Priority
byte Priority {get; set;}
property byte Priority {
   byte get();
   void set (    byte value);

Property Value

Returns the relative priority.
Remarks

"When more than one Subscription needs to send Notifications, the Server should de-queue a Publish request to the Subscription with the highest priority number. For Subscriptions with equal priority the Server should de-queue Publish requests in a round-robin fashion.

A Client that does not require special priority settings should set this value to zero."
