Equals(UAEventFilter) Method



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA Namespace > UAEventFilter Class > Equals Method : Equals(UAEventFilter) Method
The UAEventFilter to compare with the current object.

Because the UAEventFilter has an implicit conversion from UAAttributeFieldCollection, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an OPC UA attribute field collection (representing the Select clauses of the event filter) in place of this parameter, and the corresponding OPC UA event filter will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUAAttributeFieldCollection static method instead.

Also, because the UAEventFilterBuilder has an implicit conversion to UAEventFilter, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a UAEventFilterBuilder in place of this parameter, and the corresponding OPC UA event filter will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can convert a UAEventFilterBuilder to UAEventFilter using the UAEventFilterBuilder.ToUAEventFilter static method instead.

The value of this parameter can be null (Nothing in Visual Basic).

Determines whether the specified UAEventFilter is equal to the current object.

Return Value

true if the specified object is equal to the current object; otherwise, false.
