SubstituteEmptyStates Property



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.DataAccess Namespace > UADiscreteItemNode<TValue,TAttribute> Class : SubstituteEmptyStates Property
Determines whether the empty strings are substituted for the purpose of CurrentState return value.
Syntax
'Declaration
 
<DefaultValueAttribute(True)>
Public Property SubstituteEmptyStates As Boolean
'Usage
 
Dim instance As UADiscreteItemNode(Of TValue,TAttribute)
Dim value As Boolean
 
instance.SubstituteEmptyStates = value
 
value = instance.SubstituteEmptyStates
[DefaultValue(true)]
public bool SubstituteEmptyStates {get; set;}
[DefaultValue(true)]
public:
property bool SubstituteEmptyStates {
   bool get();
   void set (    bool value);
}
Remarks
The default value is true, causing the CurrentState possibly return values other than those provided by the OPC-UA server. The component author's opinion is that this is not the ideal behavior, but it is required by some of the OPC-UA compliance tests. This property has therefore been introduced to allow you to revert this behavior.
