Detailed Description
The AttributeOperand is defined in OPC UA 1.05 part 4, 7.7.4.4. It has the same purpose as QOpcUaSimpleAttributeOperand but has more configurable options.
Member Function Documentation
QOpcUaAttributeOperand::QOpcUaAttributeOperand()
Default constructs an attribute operand with no parameters set.
QOpcUaAttributeOperand::QOpcUaAttributeOperand(const QOpcUaAttributeOperand &rhs)
Constructs an attribute operand from rhs.
QString QOpcUaAttributeOperand::alias() const
Returns the alias for this QAttributeOperand.
See also setAlias().
QOpcUa::NodeAttribute QOpcUaAttributeOperand::attributeId() const
Returns the attribute id for an attribute of the node browsePath is pointing to.
See also setAttributeId().
QList<QOpcUaRelativePathElement> QOpcUaAttributeOperand::browsePath() const
Returns the browse path.
See also setBrowsePath().
QList<QOpcUaRelativePathElement> &QOpcUaAttributeOperand::browsePathRef()
Returns a reference to the browse path.
See also browsePath().
QString QOpcUaAttributeOperand::indexRange() const
Returns the index range string.
See also setIndexRange().
QString QOpcUaAttributeOperand::nodeId() const
Returns the node id of the type definition node.
See also setNodeId().
void QOpcUaAttributeOperand::setAlias(const QString &alias)
Sets the alias to alias. This allows using this instance as operand for other operations in the filter.
See also alias().
void QOpcUaAttributeOperand::setAttributeId(QOpcUa::NodeAttribute attributeId)
Sets the attribute id to attributeId.
See also attributeId().
void QOpcUaAttributeOperand::setBrowsePath(const QList<QOpcUaRelativePathElement> &browsePath)
Sets the relative path to a node starting from nodeId() to browsePath.
See also browsePath().
void QOpcUaAttributeOperand::setIndexRange(const QString &indexRange)
Sets the index range string used to identify a single value or subset of the attribute's value to indexRange.
See also indexRange().
void QOpcUaAttributeOperand::setNodeId(const QString &nodeId)
Sets the node id of the type definition node to nodeId.
See also nodeId().
QVariant QOpcUaAttributeOperand::operator QVariant() const
Converts this attribute operand to QVariant.
QOpcUaAttributeOperand &QOpcUaAttributeOperand::operator=(const QOpcUaAttributeOperand &rhs)
Sets the values from rhs in this attribute operand.

bool operator!=(const QOpcUaAttributeOperand &lhs, const QOpcUaAttributeOperand &rhs)
Returns true
if lhs has a different value than rhs.
This function was introduced in Qt 6.7.

bool operator==(const QOpcUaAttributeOperand &lhs, const QOpcUaAttributeOperand &rhs)
Returns true
if lhs has the same value as rhs.
