How to use the @alfresco/js-api.ResultSetPaging function in @alfresco/js-api

this.route.params.forEach((params: Params) => {
                this.searchedWord = params.hasOwnProperty(this.queryParamName) ? params[this.queryParamName] : null;
                const query = this.formatSearchQuery(this.searchedWord);

                if (query) {
                    this.queryBuilder.userQuery = query;
                    this.queryBuilder.update();
                } else {
                    this.queryBuilder.userQuery = null;
                    this.queryBuilder.executed.next(new ResultSetPaging({
                        list: {
                            pagination: { totalItems: 0 },
                            entries: []
                        }
                    }));
                }
            });
        }
