EasyUASubscriptionChangeArguments Constructor(HandleArguments,UAMonitoringParameters,UASubscriptionParameters)

OpcLabs.BaseLib.OperationModel.HandleArguments to be copied from.

The value of this parameter cannot be null (Nothing in Visual Basic).

Contains new monitoring parameters (such as the sampling interval, and optional data change filter).

Because the OpcLabs.EasyOpc.UA.UAMonitoringParameters has an implicit conversion from System.Int32, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the sampling interval in milliseconds) in place of this parameter, and the corresponding OPC UA monitoring parameters will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.UAMonitoringParameters.FromInt32 static method instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

Contains new subscription parameters (such as the publishing interval).

Because the OpcLabs.EasyOpc.UA.UASubscriptionParameters has an implicit conversion from System.Int32, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the publishing interval in milliseconds) in place of this parameter, and the corresponding OPC UA subscription parameters will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.UASubscriptionParameters.FromInt32 static method instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

Initializes a new copy of the EasyUASubscriptionChangeArguments object from the OpcLabs.BaseLib.OperationModel.HandleArguments, monitoring parameters, and subscription parameters.

Parameters

handleArguments
OpcLabs.BaseLib.OperationModel.HandleArguments to be copied from.

The value of this parameter cannot be null (Nothing in Visual Basic).

monitoringParameters
Contains new monitoring parameters (such as the sampling interval, and optional data change filter).

Because the OpcLabs.EasyOpc.UA.UAMonitoringParameters has an implicit conversion from System.Int32, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the sampling interval in milliseconds) in place of this parameter, and the corresponding OPC UA monitoring parameters will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.UAMonitoringParameters.FromInt32 static method instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

subscriptionParameters
Contains new subscription parameters (such as the publishing interval).

Because the OpcLabs.EasyOpc.UA.UASubscriptionParameters has an implicit conversion from System.Int32, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the publishing interval in milliseconds) in place of this parameter, and the corresponding OPC UA subscription parameters will be constructed automatically.

Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
