UADataValue Constructor(Object,UAStatusCode,DateTime,Int32)

Initializes a new instance of the class, with given value, status code, and source timestamp and picoseconds.

Syntax

public UADataValue( 
   object value,
   UAStatusCode statusCode,
   DateTime sourceTimestamp,
   int sourcePicoseconds
)

public:
UADataValue( 
   Object^ value,
   UAStatusCode^ statusCode,
   DateTime sourceTimestamp,
   int sourcePicoseconds
)

'Declaration
 
Public Function New( _
   ByVal value As Object, _
   ByVal statusCode As UAStatusCode, _
   ByVal sourceTimestamp As Date, _
   ByVal sourcePicoseconds As Integer _
)

'Usage
 
Dim value As Object
Dim statusCode As UAStatusCode
Dim sourceTimestamp As Date
Dim sourcePicoseconds As Integer
 
Dim instance As New UADataValue(value, statusCode, sourceTimestamp, sourcePicoseconds)

Parameters

value

The value of the data value.

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

statusCode

The status code associated with the value.

Because the UAStatusCode has implicit conversions from System.Int64 and UASeverity, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a long integer (representing the internal status code value), or one of UASeverity enumeration members (representing the severity code) in place of this parameter, and the corresponding OPC UA status code will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UAStatusCode.FromInt64 or UAStatusCode.FromUASeverity static method instead.

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

sourceTimestamp

The source timestamp associated with the value.

sourcePicoseconds

The number of picoseconds intervals which shall be added to the %%.

Valid values of this parameter are in the range from 0 to 99999.

Exceptions

Exception Description

Exception	Description
System.ArgumentException	One of the arguments provided to a method is not valid. 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.
System.ArgumentNullException	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.
System.ArgumentOutOfRangeException	The value of an argument is outside the allowable range of values as defined by the invoked method. 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.
