Detailed Description

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:

• arrayDimensions –

• name – str

• dataTypeId – str

• valueRank – qint32

• rhs – PySide6.QtOpcUa.QOpcUaArgument

• description – PySide6.QtOpcUa.QOpcUaLocalizedText

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

PySide6.QtOpcUa.QOpcUaArgument.arrayDimensions()

Returns the array dimensions of the argument.

The array dimensions describe the length of each array dimension.

setArrayDimensions()

PySide6.QtOpcUa.QOpcUaArgument.arrayDimensionsRef()

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.

setDataTypeId()

PySide6.QtOpcUa.QOpcUaArgument.description()

Return type:

PySide6.QtOpcUa.QOpcUaLocalizedText

Returns the description of the argument.

setDescription()

PySide6.QtOpcUa.QOpcUaArgument.name()

Return type:

str

Returns the name of the argument.

setName()

PySide6.QtOpcUa.QOpcUaArgument.__eq__(other)

Parameters:

other – PySide6.QtOpcUa.QOpcUaArgument

Return type:

bool

Returns true if this argument has the same value as other.

PySide6.QtOpcUa.QOpcUaArgument.setArrayDimensions(arrayDimensions)

Parameters:

arrayDimensions –

Sets the array dimensions of the argument to arrayDimensions.

arrayDimensions()

PySide6.QtOpcUa.QOpcUaArgument.setDataTypeId(dataTypeId)

Parameters:

dataTypeId – str

Sets the data type node id of the argument to dataTypeId.

dataTypeId()

PySide6.QtOpcUa.QOpcUaArgument.setDescription(description)

Parameters:

description – PySide6.QtOpcUa.QOpcUaLocalizedText

Sets the description of the argument to description.

description()

PySide6.QtOpcUa.QOpcUaArgument.setName(name)

Parameters:

name – str

Sets the name of the argument to name.

name()

PySide6.QtOpcUa.QOpcUaArgument.setValueRank(valueRank)

Parameters:

valueRank – qint32

Sets the value rank of the argument to valueRank.

See also

valueRank()

PySide6.QtOpcUa.QOpcUaArgument.valueRank()

Return type:

qint32

Returns the value rank of the argument. The value rank describes the structure of the value.

ValueRank	Meaning
-3	Scalar or one dimensional array
-2	Scalar or array with any number of dimensions
-1	Not an array
0	Array with one or more dimensions
1	One dimensional array
>1	Array with n dimensions
