How to use the node-opcua-types.EventFilterResult function in node-opcua-types

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
  });
}
