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.

__init__()¶

Default constructs an attribute operand with no parameters set.

__init__(rhs)

Parameters:: rhs – QOpcUaAttributeOperand

Constructs an attribute operand from rhs.

alias()¶

Return type:: str

Returns the alias for this QAttributeOperand.

See also

setAlias()

attributeId()¶

Return type:: NodeAttribute

Returns the attribute id for an attribute of the node browsePath is pointing to.

See also

setAttributeId()

browsePath()¶

Return type:: .list of QOpcUaRelativePathElement

Returns the browse path.

See also

setBrowsePath()

browsePathRef()¶

Return type:: .list of QOpcUaRelativePathElement

Returns a reference to the browse path.

See also

browsePath()

indexRange()¶

Return type:: str

Returns the index range string.

See also

setIndexRange()

nodeId()¶

Return type:: str

Returns the node id of the type definition node.

See also

setNodeId()

__ne__(rhs)¶

Parameters:: rhs – QOpcUaAttributeOperand
Return type:: bool

Returns true if lhs has a different value than rhs.

__eq__(rhs)¶

Parameters:: rhs – QOpcUaAttributeOperand
Return type:: bool

Returns true if lhs has the same value as rhs.

setAlias(alias)¶

Parameters:: alias – str

Sets the alias to alias. This allows using this instance as operand for other operations in the filter.

alias()

setAttributeId(attributeId)¶

Parameters:: attributeId – NodeAttribute

Sets the attribute id to attributeId.

See also

attributeId()

setBrowsePath(browsePath)¶

Parameters:: browsePath – .list of QOpcUaRelativePathElement

Sets the relative path to a node starting from nodeId() to browsePath.

See also

browsePath()

setIndexRange(indexRange)¶

Parameters:: indexRange – str

Sets the index range string used to identify a single value or subset of the attribute’s value to indexRange.

See also

indexRange()

setNodeId(nodeId)¶

Parameters:: nodeId – str

Sets the node id of the type definition node to nodeId.
