13 \qmltype SimpleAttributeOperand
14 \inqmlmodule QtOpcUa
15 \brief The OPC UA SimpleAttributeOperand type.
16 \since QtOpcUa 5.13
17
18 The SimpleAttributeOperand is specified in OPC UA 1.05 part 4, 7.7.4.5.
19 It is used when a node attribute is required as operand.
20
21 For example, the following simple attribute operand represents the value
22 of the "Severity" field of the base event type:
23
24 \code
25 import QtOpcUa as QtOpcUa
26
27 QtOpcUa.SimpleAttributeOperand {
28 identifier: "Severity"
29 ns: "http://opcfoundation.org/UA/"
30 }
31 \endcode
32*/
33
34/*!
35 \qmlproperty list<OpcUaNodeId> SimpleAttributeOperand::browsePath
36
37 Browse path to the node holding the attribute.
38
39 \code
40 import QtOpcUa as QtOpcUa
41
42 QtOpcUa.SimpleAttributeOperand {
43 ...
44 browsePath: [
45 QtOpcUa.NodeId {
46 identifier: "Message"
47 ns: "http://opcfoundation.org/UA/"
48 }
49 ...
50 ]
51 }
52 \endcode
53*/
54
55/*!
56 \qmlproperty string SimpleAttributeOperand::indexRange
57
58 Index range string used to identify a single value or subset of the attribute's value.
59
60 \code
61 import QtOpcUa as QtOpcUa
62
63 QtOpcUa.SimpleAttributeOperand {
64 ...
65 indexRange: "0:2"
66 }
67 \endcode
68*/
69
70/*!
71 \qmlproperty Constants.NodeAttribute SimpleAttributeOperand::nodeAttribute
72
73 Attribute of the node \l browsePath is pointing to.
74 The default value is \c Constants.NodeAttribute.Value.
75
76 \code
77 import QtOpcUa as QtOpcUa

85
86/*!
87 \qmlproperty string SimpleAttributeOperand::typeId
88
