    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
