This is the Qt OPC UA representation for the Argument type defined in OPC-UA part 3, 8.6.

The Argument type is mainly used for the values of the InputArguments and OutputArguments properties which describe the parameters and return values of method nodes.

class PySide6.QtOpcUa.QOpcUaArgument#

PySide6.QtOpcUa.QOpcUaArgument(rhs)

PySide6.QtOpcUa.QOpcUaArgument(name, dataTypeId, valueRank, arrayDimensions, description)

Parameters:

Constructs an argument with name name, data type id dataTypeId, value rank valueRank, array dimensions arrayDimensions and description description.

PySide6.QtOpcUa.QOpcUaArgument.arrayDimensions()#
Return type:

Returns the array dimensions of the argument.

The array dimensions describe the length of each array dimension.

PySide6.QtOpcUa.QOpcUaArgument.arrayDimensionsRef()#
Return type:

Returns a reference to the array dimensions of the argument.

PySide6.QtOpcUa.QOpcUaArgument.dataTypeId()#
Return type:

str

Returns the data type node id of the argument.
