Detailed Description¶

This class corresponds to the OPC UA DataValue type.

__init__()¶

Constructs an invalid data value.

__init__(other)

Parameters:: other – QOpcUaDataValue

Constructs a data value from other.

__ne__(rhs)¶

Parameters:: rhs – QOpcUaDataValue
Return type:: bool

Returns true if lhs is not equal to rhs.

__eq__(rhs)¶

Parameters:: rhs – QOpcUaDataValue
Return type:: bool

Returns true if lhs is equal to rhs.

serverPicoseconds()¶

Return type:: int

Returns the number of 10 picosecond intervals for the server timestamp.

setServerPicoseconds()

serverTimestamp()¶

Return type:: QDateTime

Returns the server timestamp for value() .

See also

setServerTimestamp()

setServerPicoseconds(serverPicoseconds)¶

Parameters:: serverPicoseconds – int

Sets the number of 10 picosecond intervals for the server timestamp to serverPicoseconds.

See also

serverPicoseconds()

setServerTimestamp(serverTimestamp)¶

Parameters:: serverTimestamp – QDateTime

Sets the server timestamp to serverTimestamp.

See also

serverTimestamp()

setSourcePicoseconds(sourcePicoseconds)¶

Parameters:: sourcePicoseconds – int

Sets the number of 10 picosecond intervals for the source timestamp to sourcePicoseconds.

See also

sourcePicoseconds()

setSourceTimestamp(sourceTimestamp)¶

Parameters:: sourceTimestamp – QDateTime

Sets the source timestamp to sourceTimestamp.

See also

sourceTimestamp()

setStatusCode(statusCode)¶

Parameters:: statusCode – UaStatusCode

Sets the status code to statusCode.

See also

statusCode()

setValue(value)¶

Parameters:: value – object

Sets the value to value.

If this data value is to be used with QOpcUaBinaryDataEncoding or QOpcUaGenericStructHandler , the value’s type must be QOpcUaVariant .

value()

sourcePicoseconds()¶

Return type:: int

Returns the number of 10 picosecond intervals for the source timestamp.

See also

setSourcePicoseconds()

sourceTimestamp()¶

Return type:: QDateTime

Returns the source timestamp for value() .

See also

setSourceTimestamp()

statusCode()¶

Return type:: UaStatusCode

Returns the status code for this data value. If the status code is not Good , the value and the timestamps are invalid.

See also

setStatusCode()

swap(other)¶

Parameters:: other – QOpcUaDataValue

Swaps this data value instance with other. This function is very fast and never fails.

value()¶

Return type:: object

Returns the value.
