    Methods

    • find the the references that are strictly of type reference.

      The isForward boolean flag specifies the direction of the references to be looked for.

      Forward direction is implied if omitted.

      • will throw an exception if more than one reference exists with the referenceType.
      • will return null if no reference exists.

      Parameters

      Returns UAReference | null

    • find all the references that are strictly of type reference. The isForward boolean flag specifies the direction of the references to be looked for.

      Forward direction is implied if omitted.

      Parameters

      Returns UAReference[]

    • find all the nodes that are referenced by references strictly of type reference.

      The isForward boolean flag specifies the direction of the references to be looked for.

      Forward direction is implied if omitted.

      • will throw an exception if more than one reference exists with the referenceType.
      • will return null if no reference exists.

      Parameters

      Returns BaseNode<BaseNodeEvents>[]

    • return a complete name of this object by pre-pending name of its parent(s) to its own name

      Returns string

    • get effective accessRestrictions if (inherited is true) and node has no accessRestrictions, then default accessRestriction from namespace is returned if (inherited is false) and node has no accessRestrictions, then AccessRestrictionsFlag.None is returned

      Parameters

      • inherited: boolean

      Returns AccessRestrictionsFlag

    • Parameters

      • Optionallocale: string

        the locale of the text to return (e.g. en-EN)

      Returns string

    • Returns boolean

    • Parameters

      • n: number

      Returns void
