    AttributeOperand Class

    Extends FilterOperand
    Defined in: packages\node-opcua-service-filter\_generated_\_auto_generated_AttributeOperand.js:29
    Module: opcua.address_space.types

    Constructor

    AttributeOperand

    (
    • options
    )

    Defined in packages\node-opcua-service-filter\_generated_\_auto_generated_AttributeOperand.js:29

    Parameters:

    • options Object
      • [nodeId] NodeId optional

        NodeId of a Node from the type system.

      • [alias] String optional

        An optional parameter used to identify or refer to an alias. An alias is a symbolic name that can be used to alias this operand and use it in other locations in the filter structure.

      • [browsePath] RelativePath optional

        Browse path relative to the Node identified by the nodeId parameter.

      • [attributeId] IntegerId optional
      • [indexRange] NumericRange optional

        This parameter is used to identify a single element of an array or a single range of indexes for an array. The first element is identified by index 0 (zero).

    Properties

    alias

    String

    Defined in packages\node-opcua-service-filter\_generated_\_auto_generated_AttributeOperand.js:59

    An optional parameter used to identify or refer to an alias. An alias is a symbolic name that can be used to alias this operand and use it in other locations in the filter structure.

    browsePath

    RelativePath

    Defined in packages\node-opcua-service-filter\_generated_\_auto_generated_AttributeOperand.js:66

    Browse path relative to the Node identified by the nodeId parameter.

    indexRange

    NumericRange

    Defined in packages\node-opcua-service-filter\_generated_\_auto_generated_AttributeOperand.js:80

    This parameter is used to identify a single element of an array or a single range of indexes for an array. The first element is identified by index 0 (zero).
