How to use the node-opcua-address-space.checkSelectClauses function in node-opcua-address-space

function analyseEventFilterResult(node, eventFilter) {
    assert(eventFilter instanceof EventFilter);
    const selectClauseResults = checkSelectClauses(node, eventFilter.selectClauses);

    const whereClauseResult = new subscription_service.ContentFilterResult();

    return new subscription_service.EventFilterResult({
        selectClauseResults: selectClauseResults,
        selectClauseDiagnosticInfos: [],
        whereClauseResult: whereClauseResult
    });
}

function analyseEventFilterResult(
  node: BaseNode,
  eventFilter: EventFilter
): EventFilterResult {

  if (!(eventFilter instanceof EventFilter)) {
    throw new Error("Internal Error");
  }

  const selectClauseResults = checkSelectClauses(
    node as UAObjectType,
    eventFilter.selectClauses || []
  );

  const whereClauseResult = new ContentFilterResult();

  return new EventFilterResult({
    selectClauseDiagnosticInfos: [],
    selectClauseResults,
    whereClauseResult
  });
}
