Property Documentation
Alias name for the operand. This allows using this instance as operand for other operations in the filter.

Attribute of the node browsePath is pointing to. The default value is Constants.NodeAttribute.Value
.
import QtOpcUa 5.13 as QtOpcUa QtOpcUa.AttributeOperand { ... nodeAttribute: QtOpcUa.Constants.NodeAttribute.Value }
Node id of the type definition node. The operand will be of the type or one of its subtypes.
